the concept is interesting, the game feels way too difficult to be fun.
Since this is a 3d/first person game, i cant see all the enemies like in the classic survivor-likes, so i end up bumping into enemies from all directions.
healing - could not figure out why i cant just pick up those apples. hitting R did not seem to work either, strange.
upgrades, as stated by others, the small % to X upgrades are bad.
