A nice and polished puzzle game.
Notes:
Lol @ the Japanese voices.
The menu text is very hard to read, a bad font. The first screen also goes way too fast to read what's written on the bottom.
For the breaking holes, I expected falling through one to do a flip, like the flip tiles do, not kill you. That's an inconsistency in the gravity logic.
Missing sfx for things like lasers, getting hurt, etc.
Some things on the title screen are outside the safe TV area.
