I like the new name!
Good work!
Here there !
I wanted to congratulate you on the great work you did on the demo!
It was nice to play, and the effort you put into it is visible!
The only problem I encountered was that the drill camera view was shaking too much in fullscreen, I think it can be reduced (it made me a bit nauseous), but the windowed mode was ok for me ;)
Additionally, I could explore a cave and get lost for some time; a minimap could be helpful.
I wish you success!
