I really like the rat model, it looks cute. It'd fit an action-adventure type of game. I like the crafting system. After reloading, it didn't lag for me anymore (likely cache?). After crafting arrows and crossbow I couldn't shoot it. Not sure why, should I have pressed some button to load them...? I loved the music! A smoother transition between the 2 tracks would be nice. Also, after some time the music just stops playing, is it set to loop?
Great job on the game!
