The level of polish, with the effects, particles and animations is really, really good. The game feels GREAT to play! The spear don't always face the direction I tell it to go, it's a bit frustrating, but maybe I'm missing something xD.
So yeah, it's a really good and fun game... But a bad Brackeys Game Jam entry, since you totally got rid of one of the two major constraint of a game jam: the theme ^^'... So I must admit that I don't really know what to do with that xD!
