I really like the visuals of the game! I did a similar 2D art style in a 3D space for my game!

Wow, this is almost a complete game. It's well polished, has good sound and music, has progression, has an options menu, has skins, features a leaderboard, it saves your skins you've unlock, and it's quite visually appealing. I'm really impressed that this was completed in just 7 days. Well done. 

The only issues I can come up with is that it's sometimes hard to tell which tile certain items are in. If you get stuck without any torches with some enemies, you just have to wait as they slowly whittle down your health in order to kill you. Finally, there isn't much to give inevitability in the game other than food becoming less and less effective. Being able to fully heal after each level makes it really hard to die if you just rush through avoiding all enemies (which are very difficult to kill and give almost no reward for being killed). Also, it would be nice to be able to turn in place.

I didn't mean to give a full paragraph of criticism. I suppose I'm treating this game like it's a full release because it is that kind of quality. Amazing job with this game.
