It is an enjoyable short game and I like the visuals too.
Perhaps a simple audio slider for those who find the game too loud?

Pretty cool concept of a puzzle dodging game.
One problem I have is that the upgrades doesn't felt like it made any significant impact, though you could probably remove the upgrade system and it would feel fine.
The other is the design of levels, where some levels just felt like an identical to another. And maybe you can modify the playing field where it isn't always a cube.

The level design is pretty decent but there needs to be something interesting/challenging once in a while, something to keep players on their toes/excited once in awhile.
Won't really complain about the UI considering that it is made for mobile.

Other than the sound not working for me, the game was pretty decent to play for awhile.
