"A pretty simple game I will admit, but hey I'm mostly here to learn :D" - A wonderful sign of a humble game developer. A mindset in game jams that only the top 1% have (fact checkers say this 1% is wrong 😂)
The art-style is uniquely attractive. I can say that this art-style & this game feel has potential to be a bigger game. Albeit the core 'breathing' mechanic could be modified to make more gameplay elements and the level design will have to be adjusted as well but that is only FOR A BIGGER GAME.
The game right now as is, does what it's supposed to do excellently i.e. deliver a game experience smoothly. which is better in my 2 cents opinion than having a big game deliver a bad game experience.
Fantastic job, Hope you learned a lot from the JAM ( I again will say that your art style is unique & holds a very 'true' to you identity )
