Really interesting idea! This is kinda the Ikaruga I've always wanted to play... It's hard to properly pull off reflections, but when you land a hit it feels SO GOOD.

The polarity is fun to play around with. Takes a bit to get used to balancing it with the reflection.  A good twist on the arena shooter formula. Also I had some kind of glitch where sometimes the reflect wouldn't work even my stamina had charged back up, I think it usually happened after a polarity shift? Couldn't figure out exactly why though. Good job!

It doesn't work for me under linux, saying that there is no data folder.
