Great work! The art is amazing, nice music, and the gameplay was fun!
Not sure if the inputs get more complicated in later levels but, if not, it could be interesting to make everything playable with just WASD -- menu nav with W/S, A as back, D as confirm, on the level start screen, W for "Begin " and S for "Main Menu", and D for dialog progression, etc. Not sure if it would actually work that well but it was just a tad inconvenient reaching for the mouse occasionally (or maybe I'm really just that lazy).
