Great game! The first level was very frustrating, and it is disheartening to have to re-acclimate yourself to new controls each time you die. But in the later levels you do some really fun and interesting stuff. I would recommend just decreasing the difficulty of the first jump since there are no other jumps like that in the rest of the game. I was not able to get past the level with the two code, maybe I was missing something. Music presentation and theming are all great, it reminded me of the game Mooncat which is one of my favorites. Congrats on a great first game jam entry! Look forward to seeing what else you make!
