Playability:
Incredibly interesting take on faalling block games. Would love to see more gameplay implementation here but it seems you ran out of time. Keep working on this. Unique piece.
Theme:
Fits the theme loosely but could change with more time spent developing it. Nice work so far.
Cleverness:
Haven't seen a falling block game like this. Creating tiles in this way is really interesting. Maybe a tile phase and then a placement phase? Lots of interesting directions here.
Artistic Style:
Simple, consistent, and pleasant. Overall nice and easy to understand.
