Very nice models, textures and sounds. I have only one feedback: I liked the sounds for picking up different items but for stones, the sound effect is kinda "low"! I mean it sounds like your are picking gravels. Maye it needs to be more "deep"?

Excellent, I see no problem! It is so polished and obviously you have great attention to details.

Sound effects are good to me. Although is that background noise or the menu background ambient track. Either way I think it kind of suits. The clicking noises when hovering over buttons is good too. I'd say as someone that has zero experience with sound and has done no work with it on my own project. Quite impressive

Solid progress so far! I do not know if it is still work in progress but enemies falling down animation needs more improvement.
