really awesome and fun game to play! however you went so far to crew-create the Gameboy but not really the screen. If you look at the game F-Hero that was also apart of the jam, he made it feel like that dot-matrix LCD crystal. I think if you would have added this to your game it would have really rounded the project off as a nice clean complete thing.
Another thing i noticed, after awhile playing either of the games, the sound just stops. Not sure if this was an oversight or not or as intended. When the music turned off the game became a bit dull because there was no pickup or accomplishment sounds. Other then that this was super fun!
