I really like the mechanics of this. The way the enemy numbers increase as you move really makes you think about your actions, you try to be as efficient as possible with last second dodges and efficient collection. I like the way you can see where the enemies are going to spawn on your next move, too.
The music and sound design is nice, though maybe a game over theme would be nice.
Tough as nails, though.
My biggest complaint is the tiny screen size. I sit quite far from my monitor so it's really hard to see anything1
