(I am now in a rush to test as many games as possible to help, so please do not mind the cursory reviewing style.)
controls are QWERTY-only instead of layout-independent, BUT arrow keys are enabled
This is super original! :) … Yet, how is it die-related?? :o I can see how this is Tetris-related, though! ;)
The explanation you gave in the form amounts to have added some randomness, but I think the connection is a bit weak. No worries though, the game does not get judged on that criterion. X)
good idea having written the names of the powers/abilities!
Managed to beat it! :) The levels were reasonable, and the time counters give an incentive to try again.
The powers play well, very pleasant to play!
Just weirded out how it does not seem die-related (except if you interpret Tetris pieces as able to form a cube?), but otherwise, I like the game, for its originality and gameplay. :) The visuals are also rather nice, although simple, which is fitting seeing the universe chosen.
