If anybody manages to top this let me know!
Really polished pixel art, nice to have the time to explain everything carefully.
@david-york Your character has a monitor on their head. This monitor holds two pieces of information, but it only shows one at a time. The first piece is a number from 0 to 9. The second is an operator (add/sub/mul/div). Pressing SELECT switches which of these you are editing, and pressing A or B cycles within that category.
On the map there are a bunch of little stations. Each station has a screen showing the operation and number loaded into it, and a pad to the left of the screen where you can stand to copy the contents of your head into the station. These stations start out configured to add 0, so they just pass whatever input they get directly to their output until you adjust them.
At the right side of the map there are two other screens, one with the target number and one with the starting number, and a third screen to the left of those containing the final result you've computed. The starting number flows along wires in the ground, going from station to station in a clockwise order. At each station, the operator/number combo that's been loaded in will be applied to the input, with the result carrying on to the next station until it reaches the result screen. Your task is to configure as many of the stations as you need to with whatever settings are required so that the result number matches the target number.
So for example, say the starting number is 17 and the target number is 39. You can solve this a few ways; the way I'd do it is to first double the 17 to 34, then add 5 to bring it to 39. To do that, you set your head to 2 using A/B, then use SELECT to switch to controlling the operators and use A/B to change that to *. Then you go stand briefly on the pad for the first station (bottom-right). That'll configure that one to do the doubling, and your result number will now be 34. Next we need to do the addition: get off the pad, change your operator to + and your number to 5, and stand on the pad of the second station (leave that first station alone; you don't want to undo your work). Once it's loaded, the result should now be 39, so you can press START to submit it and begin the next puzzle.
Thanks everybody for the kind comments!
Bonus points to anybody who manages to find the secret ending (There IS one way around the inevitable...though I worry it may be a little to obfuscated).
I played on the web browser but I will try with my GBASP
The only thing I had issue with where the controls, it took a min to get familiar with them. Otherwise, the game is amazing!
@kurrik Thanks for the feedback! I agree completely, I think rearranging the map and including another gameplay element would have really helped speed it up a bit.
Thanks for playing!
@tigerj Thanks for sticking it out! That 2-bit palette on the Game Boy really makes pointing out crucial features somewhat challenging...watching you figure out was super useful feedback though!
Pros:
- I love the design. The colour palette is exactly what I would thought of when launching it on Gameboy system
- Interesting mechanics, yet easy to understand
- I like how simple maths can get tricky very quick
- Demanding gameplay (on a + side ofc)
- Good difficulty scoping
- Tutorial is a plus
- Nice soundques
Const:
- I think it should have been divided into two levels. One to grasp the actual concept of connectors (with maybe 2 magistrates), so the user can get along with the mechanics before being thrown into the bigger map
- I think the character design is great, but I don't like the idea that you're missing the context of the character when your'e moving left right and up. I believe a better design would be for the character to have 'around screen' face, so player always sees the context of the information regardless of the sprite positioning. I hope you understand what you mean
But those small caveats cannot overshadow the fact that this It's an excellent entry and definitely a one to look at for the high spots. Great job!
If you ever want to go further with this I would add a way for the player to see the target number without having to search for it on the map. With a small map such as the one you have it works. It forces the user to waste time to go look for it, but as a game outside this jam's theme I think it would be interesting to add an extra cycle to the character's screen that displays the target and current values maybe?
I loved this game, big fan of gameboy games :)
Very well done!
Great work !
A bit difficult for me as I'm not much into numbers haha, but I still had a lot of fun :)
@zombiebust3r Thank you! The ROM plays great on the original Game Boy, I actually have my highest score on it!
@vhalenn Thanks! I updated the image on the itch.io page to hopefully help with this a bit...but I think adding a small and optional tutorial at the start will be the real solution, thanks for the feedback!
@zoohair Thank you!
@epu Thanks! So glad you got to enjoy it on the best platform (it runs shockingly well on the DMG, and the controls feel way better there IMO)!
@dannyk1994 Really appreciate you giving it a go!
Graphics are decent, the audio can become a bit annoying though.
@stefan-laimer Thank you!
@alexthehuman2 Thanks again for playing and really enjoyed watching you piece it all together and kick some math ass!
It's just so unique, and making math fun seems impossible, yet here we are!
First off, thank you for the tutorial video, it was really helpful.
Audio, visual, mood, graphics, everything blended together so well into an awesome retro experience! Having to do math on a timer is stressful in a fun sort of way lol.
Congrats on this awesome entry!
Great work, will play this again later!

that is a loot of money
It may be asking a bit much since theres already so much to enjoy, but an in game tutorial would have been really nice
Also is there an S grade

Neat game, had a great time playing it on emulator. For some reason I thought I had to press START after stepping onto the pad to send data to the register (and previously missed that I had to press START to confirm a target). I really appreciated that I could put things into registered and get immediate feedback on how the number changed, so I could combine estimated mental arithmetic with a test-and-update loop to get to the result quickly rather than having to do it all in my head. Supports a variety of thinking styles.
The game is great, I love the graphics, brings me back in time. Also the geeky theme is lovely!
Controls are a bit weird on keyboard, too bad I do not own a GameBoy I bet it's even better on it!
For a compo entry this is truly awesome!
I love puzzles and they fit very well in the console. This one is quite unique and they really play well and the graphics are fanstastic. A superb entry!
@hmightypirate Thank you! If you like game boy games and you enjoyed the Compo version you might like the more finished and polished version that can be found here:
https://foxwater.itch.io/ludare-os-triple-dare-edition
Even though I am not the biggest fan of the gameplay (felt a little bit repetitive after some time) I actually played the jam version and the triple dare edition and have to say that I am amazed on what can be achieved in that little time!
@ulisses Thank you! I'm really glad you enjoyed it
