Very cool! I got to round 5 with 12,245 points.
Felt very Metroid Prime-inspired, specifically Metroid Prime Hunters arena multiplayer on the DS. Down to the aesthetic, the HUD, music etc, big fan of that. Having to adapt on the fly to what your next shot type will be is fun, especially when it makes you aim differently like the arcing shot of the bomb or trying to line up enemies with pierce.
Minor gripe, I wish it was easier to tell which shot you had because I found myself having to look up at the top right a lot to read it. I also never quite figured out what the Revitalizer did, I assume it heals you somehow?
But this looks and plays great, and I could totally see it expanded with more enemies, levels, power-ups, or movement options. Well done!
