I felt so much Gameboy vibes, that's amazing !
I liked the exploration gameplay.
However, there is a few points that makes the game a bit unpolished : the lack of tutorial for digging upwards and downwards, the weird hitbox of the axe.
Another thing is the lack of music, fortunately, there was SFX
The map was huge, and I wasn't able to see everythiing after dying multiple times.
Congrats on this game !
