This is a funky idea. Love the ingenuity of it and how innovative it is. I don't think it plays particularly well, though; it feels very disjointed in how you have to hold a different button to dodge and, when you're doing that, it inevitably throws off your aim so you have to target the foe again. Then the projectiles are of questionable readability making it hard to tell when and how you should dodge. A fast-paced fight can feel like a slog. There's some kind of false dichotomy to the shooting and dodging that I can't put my finger on.
The flying drones that move in a square are really boring. Flying in a predictable pattern, it's easy to stand somewhere they can't hit and just try to follow them until they die. Basically just holding a button on them until they fall over. It's not really engaging.
I really like the character designs. You've done an amazing job with lineless pixel art with only up to three colours a character and making everyone stand out and even having their own accessories. Very well done.
