I like the novelty and I think the concept is pretty cool. I think it's a bit weak thematically though, as you could swap out the 1s for 2s or 3s and it'd be the exact same game. But I dunno if that matters really, the theme was the launching point that led to this idea and I had fun with it so... good job! Also, I agree about respawning near the walls quickly, lost a couple of lives that way.
