The graphic was surprisingly rich for a 3D game. I was impressed by the level of details of the snake's head, it must have taken a lot of time to create it. You also managed to make different musics, the first felt a bit too repetitive (and was very loud) but I think it is more a matter of personal tastes in music, so I think you made an excellent job also in this part.
Unfortunately, when going back to the checkpoint the camera gets stuck in a fixed direction so I was unable to complete the game.
It felt like a bit like a No Man's Sky planet mixed with a Minecraft user interface. The blocks emerging from the acid also made me think of Mass Effect Andromeda.
