What an awesome puzzle game! It's such a great combination of a very interesting mechanic, and clever levels!

It was short, but each level made me think long and hard to figure each one out. They were all super clever and it was a thrill to be able to solve them!

Mechanically, it's very smooth. The cause and effect seemed quite clear, and it was very nice having the sound effects for each action so it never feels like there was no feedback for something happening. The undo button was a blessing, and made the game much more forgiving to play, which for me was another bonus. I'm not exceptionally good at puzzle games, and it definitely removed the aspect of frustration from seeing the correct move after making an incorrect one!

The art was very clean, and I think the simplicity of it made the puzzles much more legible as well. The bold red was a great choice for the intractable object.

Overall really well done! I can only hope you'll make more levels sometime! :D

It's a quite hard game especially for people who are not that good in the puzzle, but still, very well-designed. I like the color and the background music, simple but joyful.

One thing that I want to suggest is that maybe you need to explain first or make a guide level to tell players their goal is moving the character to the flag. The first time when I played I misunderstood that I should push the portal (and I don't know this is a portal) to the flag.

Also, I think the game is not that related to the loop? Could you explain a bit more about your design idea?

But still, it's a good game for puzzle fan.

awesome puzzle.

I am not sure if some of the puzzles I got lucky and they just look harder than it really is. I would actually love to see this idea expanded on.

I didn't understand the mechanic at first, I thought it rotated the tile. Only at round 2 then I clearly understood that it was swapping the tile. I managed to get to the end and I really enjoyed it.

Thanks for the game !

Edit: I just realised the name of the game LOL .. should have realised it was swapping and not rotating.

Great puzzle game concept. It took me a little while before I figured out what pushing the red ball actually did. A intro level or two to introduce the mechanic would go a long way with teaching the player how it works.

The graphics and audio were both very well done and fit together perfectly.

Overall great job!

*I ran into one crash on level three when I reset from the menu, but I didn't capture the error message.

@benbennett thanks for the comment and the bug report! I think I've fixed it now!

@yangying The relation with loop is that usually at the beginning of the level, the player is stuck in a loop. I build the mechanics aronud the idea, yet it turns out the levels are different from what I've expected.

I'm definitely aware of the misleading mechanics at the beginning, but I didn't have enough time to make enough puzzles, hahah sorry

Very nice aesthetics, a bit confusing at first but very solid entry!

I restart many times to draw the map:) Simple rule, but Good level design, I wonder more usage of exchange

I was real bad at this game, but it's super intriguing! I got hooked on the puzzles and spent a long time trying to work them out!!

Once i (finally) figured out what was actually going on with the swapping and the red circles, was a fun puzzle that was satisfying to solve.

Super clever puzzle mechanic! I find it too hard to simulation in brain, yet it is fun to experiment.
Also interesting use of the theme, as "can only walking along a looped path (at start)"

Awesome puzzle game! Had to restart it a couple of times but have a nice "baba is you" feel.

I'm very impressed by the concept. This is such a clever game mechanic. I really enjoyed playing this one. Well done! :D

Good game, it's very difficult!

Great puzzle game! I love the usage of Pico8 engine :)

Great game! Really well thought out and executed, great work!

Very creative puzzle game! I feel a little difficult

That is nice puzzle. It is so challenging but I manage to clear.
But, I never understand how to solve Level 2. (I'm sorry I change the code to play 3 or more levels)

Overall, that is fun puzzle!

*I can push red bubble to move diagonal, it is intended?

@hiko-game Oh I'm sorry for that. That's a bug I've fixed on itch, yet haven't push the changes to GitHub. Level 2 is a bad level tbh, you need to quickly move onto the tile after pushing the red bubble.

Wow, you came up with a great original puzzle game idea, and you managed to create many interesting levels!

This was hard, but I made it to the end!

前有蔚蓝，后有Swop:D A great polished game!

Cool mechanic and nice levels (except level 2 :D)! It doesn't seem too thematic to me, but that's okay.

I'm curious how many different "paths" or "reachable states" are there on a level. :thinking: I might've kinda brute-forced some of them. :sweat_smile:

Just finished playing, and I liked the concept of the puzzle. In particular, it's nice how Level 1 teaches two important rules at once - the swapping when the next tile is right beside the bubble, and the traveling followed by swapping when the next tile is far away.

It slightly bothered me that the rule presented by Level 2 - that the player can move while the bubble is moving and this isn't a turn-based game - wasn't needed in any other level. But this is only me nitpicking, really, it's a great game overall!

A really interesting little puzzle game! Properly mind bending at times - I'm really thankful there's an undo button! I feel like I brute forced my way through a lot of the puzzles - I can't imagine what designing them was like! I enjoyed the music too - simple, but effective, and it's always nice to have some BGM. Some extra polish would have made it sparkle - but it's a really solid base.

Tricky but simple puzzler. Music is nice too. Good Work!
