That was really cute! Well done, I like the forced initials, and overall it was a good blend of a few time periods of game. And the whole bubble thing was super nifty.

The whole death thing is a little harsh here, but the idea of severe penalties for missing is intriguing. I wonder if a game where missed shots turned into enemies, or somehow increased the negative forces against you would work. (Hmm, or go for a seesaw, where missing powers you up... but I guess you would want to make it so you can't just grind your power up... hmm...)

Neat though!
