The art style is super cool and I really like the world you've built!
However, the gameplay itself is definitely lacking in comparison. I did not understand why I wasn't drilling the rock until I saw in your gifs that you were also moving the character in circles together with the handle to actually do any drilling. I also realized that you don't even need to spin your character and just spam opposite directions (eg. Left and Right) to speed run through the game. The game also lacks a lot of feedback for the player other than the slight screen shake from a successful drill and the heavy breathing on the player when they are low health. If you are not planning on providing any in-game tutorial for the player and want to make them discover the mechanics themselves, the controls should be intuitive enough for them to do so.
Other than the gameplay, I really enjoyed the world and atmosphere that you've built!
