I feel like it's pretty close to being a perfect little exploration game - even without going far beyond current content. Also very beautiful and well-optimized in that. My first beef - turning around feels uncomfortable, i wish it could've been done without stopping. Second - I wish there were some pointers on how far I'm in my mission or if it is done - reminder that I can leave and where, Like I found one chest, and not sure - is it done? Should I get back from were I starte?. A bit confusing. Anyway, TLDR - pretty great game!
EDIT: puntuation.
