Wow, I wasn't expecting that. Shooting while moving side to side only, but each blaster is a life and if hit and a blaster is removed, can only shoot when moving in one direction, or none at all. Really clever and makes you think more about your placement. Couldn't find a way to regain health/blasters if possible but the special attack is pretty helpful. Difficulty spikes pretty quick but otherwise, everything else feels pretty cool and fun to me!
Also noticed that layers of the music would unlock based on progress of some kind? Or maybe just a coincidence but still, I'm a sucker for that kind of stuff.
