I like your game, I like the pit, I jump it in a lot maybe you add something here like a goofy or scary thing the make it spicy. I like the idea that throwing things in the pit.
I have 3 feedback
1 Game feels laggy (maybe my computer is responsible for it)
2- When I take the cube and walk cube move with little vibration I do not how to explain it and you probably realize it. It bugs me a lot.
3 When tutorial say open the store with E I did not see the store and I geniunely try 15-20 times to just press E lol. And when I try to find a store or something I accidentally find the mine. So maybe you should indicate it. Also store screen shows a lot of upgrades at first which feels little bit complicated.
