I really liked the core mechanic in this game. There's a lot of potential to it and I think the mechanics currently there are already a pretty good use of the tool kit.
I think the idea of relying on a natural tutorial rather than specific instructions is pretty good for a platformer but I think it probably could have been done in a bit more forgiving way, I spent a bit too long on that first spike jump a bit unsure on how to actually solve it.
Some of the level design in general can be a tiny bit too precise, some of the levels felt more trial and error than anything but I think that could easily be ironed out.
It's a shame the game lacks sound since I do think the drill lacking it make it a lot less impactful and it would add a lot to the experience.
Still this is a pretty good proof of concept and I'd definitely be interested in seeing those mechanics developed further!
