Something seems to be off in the movement—the way it seems to move the enemies never really quite made sense to me. However, the quick restarts in the game got me to keep playing for a good while, and eventually I got used to it enough to at least be able to chain together some wins in a row, which felt really satisfying.
I didn't feel like the ten second limit was necessary, as I never really had the opportunity to live that long, and the objectives were enough of a motivation anyhow.
So overall, I think there's room for improvement, but I had fun :)
