I like the premise, and I really love the twists your game has. Good job on the UI too. I have two simple suggestions.
The game feels tense, but also a bit slow. Tweak your movement speeds just a bit, just enough to make the game a bit more satisfying.
I love minecraft! But the wooden floor texture feels really rough on the eyes. Maybe just make it a bit lighter or less saturated so that it's easier to look at for longer periods.
But overall, wonderful job! I hope you keep making cool games :)
