This is aggressively polished, nearly to the extent of an indie game release. The music is pleasant, the font and sprites were cool, and the concept was spot on. It even has interesting story elements.
I couldn't tell if it was intentional, but the enemies that shoot all directions at once (that kind of resemble bees?) still move when time is frozen.
There are also a couple of ways to cheese the gameplay loop... If you run into a wall, as long as you're holding a direction key, you will still stop time without having to actually move. And of course you can always spin in a circle if you need extra time to think without ramming yourself into a corner! It may be fun to have the game recognize when the player is trying these and to do something more interesting with it.
[Oh and obligatory comment that I submitted in the same genre, but mine is far more incomplete and amateurish.]
