It is criminal how no one has played this yet as it is a really well-thought-out puzzle game. It was a really cool idea for you to be a cleaning robot too, as that added another layer to the puzzles. I was particularly proud of myself for solving this level:


Would love for this game to have some music, sound effects, and other game juice, but I understand that time is limited, especially for a solo developer such as yourself. Overall really enjoyed this, and I hope other people find it and enjoy it too

I like the mechanics of this game and how you have to balance the cleaning trash and moving lazers. There is a fun tension there. I think the levels are slightly too large and should be more focused on individual mechanics, especially at the beginning of the game.

Adding sound effects and undo would improve this game a lot.

Overall, this is a very good puzzler, I had fun! :)

Good puzzle game. But I'd like to see more feedback. It would be great if you added some sound effects and music.

Good puzzle design is so tough to pull off in a game jam because it benefits so much from playtesting, but I thought these puzzles were excellent! Very challenging, but not impossible. I do agree with a previous comment that an undo button would go a long way to reducing frustration in long levels. Playing as a robot vacuum is a really cute idea and I thought the art was charming. Great job on this one.

@Meemog Thank you very much for your kind words, they mean a lot to me. Level 3 was also my favorite :)

@juyr I'm glad that you like it :) I was a bit afraid the trash part would just be an added annoyance, as I struggled to tie them together. The level size kept escalating a bit too fast, that's true. It was just easier to make larger designs than to make intricate ones.

@shimiki Thanks :) Yeah, I had to fight with the feedback. I'm unfortunately so bad with sound design and implementation that I focused on the two monitors showing the progression of the two puzzle parts. One day I will try to make a game with proper sound!

@itisthelaw Thank you, I'm happy you liked the difficulty level :) I had no playtesters this time, as I only managed to create the levels in the last few hours, after spending most of my time creating the basic mechanisms and removing bugs (there are plenty left, though). An undo button is a good idea, I did not think about this at all :O

Really neat game with graphics that reminded me of Space Station 13. Also challenging :) Can't imagine how one can make a game of such level through a gameJam. A job well done!

This kind of cartoon characters with a slightly pixelated style and the level-clearing format is quite novel! It's about forming reflections by choosing the right angles to connect the correct signal circuits, which is very in line with the theme of signals. The developers have put a lot of effort into it. There are also some reward mechanisms and even rotten bananas, hahaha. It would be even better if there were a little sound effect.

A solid puzzle game with a clear connection to the 'Signal' theme. I liked the concept of the cleaning robot on a space station!

To take this to the next level, I’d recommend focusing on 'Quality of Life' features, specifically an undo button. Repeating the same steps after a mistake can pull the player out of the experience. Also, even some basic ambient sound or 'beeps' for the robot would go a long way. Overall, a clean and functional entry. Well done!

@disastra Thank you for your kind words. I take it as a compliment to my very basic pixel art skill that it reminds you of that.

@zhangzhimu Thank you very much. I'm happy you liked the bananas. Next time I even try to create a sound effect for them ;)

@imnotvegan I have to admit that the concept of the vacuum robot came from my lack of artistic skills. I started of with an orange circle as a place holder for the character and just had a solid dark blue floor. That looked somewhat like a goldfish in space, but the circle gave me an idea for the robot!
Unfortunately, the thought of an undo button never crossed my mind... Thank you for your feedback :)


I really like the game! The last level was quite challenging and having to restart the whole level after a single mistake made it brutal. As others have said, an undo button would be nice. Music, sound effects, and a way to go fullscreen or resize the window would all go a long way in making it feel more polished. Great work!

Great game! The last level took a lot of retries due to the amount of foresight required. But it was very satisfying. Having multiple goals (power, clean, get to base) allows for a lot of neat situations. Also, props on creating so many assets. It was nice to be able to vacuum a variety of things :smile:

My only note is that the dirt can be hard to see on the noisier patterned floors. Thanks for the great game!

Great stuff, really enjoyed the puzzles - I struggled on the last one mostly forgetting each time how I escaped the first room with all the boxes :smile:

Cool touches with the random dirt objects , and the combination of having to clean up as well as fix the signal. I got confused initially thinking the wires were somehow interfering with the signal and the signal itself was dirty ( not the ship! )


Realy good game, its a bit hard, i wish there was an undo feature cause its not great to have to restart the level if you mess up at the end but besides that great job!

Well designed puzzle game. Very nice!
I do have a slight issue with the controls, they seem a little unresponsive when it comes to stopping movement; so many times I overshot my target. But it's still a well made puzzler!

I believe, this game have a great potential, PLEASE, fifnish it with sounds and more levels!!!

And yes, it IS frustrating to start over, because the game is hard (good level of hardness))

Also, check this bug: 

It was a good puzzle. It was a little complicated, but it was fun.

Made it all the way to the end! I do like how the puzzles ramped up in difficulty as the game progressed. The last one actually stumped me for a little bit (but I eventually figured it out). I like the premise, but it did feel like cleaning up the litter and resetting the lasers didn't really have much impact on each other since you could often just do the cleaning completely before focusing on the lasers. That said, I do appreciate the variety of litter objects since it adds a bit of charm. Overall, not a bad entry!

This is a fun little puzzler! Love the space station vibe, and the graphics are both cute and effective for communicating puzzle mechanics. I always like a laser deflecting puzzle, so it was a good time. The last puzzle was especially clever - realising I had to undo and then redo my own solution to get to the exit was a cool twist.

I think a few mechanics could be improved on - the trash collecting doesn't add all that much right now, other than that sometimes you can mistakenly lock off a piece of trash and have to reset the whole level. The little corners with random stuff in them all to hide a piece of trash just distract from the puzzle. On that note, an undo button is sorely needed! The levels tend to be a bit cluttered with boxes, and it's extremely easy to softlock yourself. Redoing the whole level whenever this happens can be tedious. The addition of an undo feature and tidying up the levels a bit would really help the experience.

On a audio note - while I totally get not have time for it during a solo jam, in my opinion music and SFX should be your top priority if you choose to continue development. SFX are crucial for the feel of a game, and music ties the whole thing together.

Great work!

Cute entry that combines Sokoban with Beambender. While there are not many levels, the puzzling is non-trivial and the amount of content is perfectly bite-sized for a Ludum Dare playtest.

I wonder whether the bug that sometimes lets beams continue to spread even when their source is cut off could be turned into a feature.
