Loved the art style in this game, was really nice (Only wish I could rate you on that)! The knife weirdly randomly stopped working for me, even though i had like 80/90% stamina, dunno what was going on there. As I've said to others, I'm not a big fan of mixing keyboard and mouse on side scrollers, would have been nicer to have a key option there :) Good effort dude!
Edit: Also please remember to remove the SteamVR stuff when building your game, it keeps opening it when I launch your game :P ( I think it was yours)
