Thank you for playing! The initial idea was to make a metroidvania containing 4 areas (game idea, programming, art, music) with a boss fight for each. Obviously, since I'm still learning how to make a game that was impossible. I spent a lot of time making one boss fight and only had a few hours to make rush the content before it. The result is a mediocre platformer full of bugs as you correctly said, but I learned so much during that week that it was totally worth it :)
By the way, I wanted to play/rate your game but there was only the Windows executables and I'm using a Mac. If you have time for your next game, please also compile for Mac or at least WebGL. m(_ _)m
