This game is aesthetically excellent. The art is phenomenal, the animations are really fluid, the music slaps, and the UI is extremely clean.
The gameloop is short and sweet, I enjoyed the variety of characters you introduced and working out how to adapt to them. I really liked the way time slowed while launching, but I did then spend most of my time in 'launch' mode to make lining shots up easier, which I assume wasn't the intended approach.
The controls did take some time to get used to, but I think if they were rebound/I played on controller the gameplay would be a lot more intuitive.
The foundation is really solid, I could see how you could build off it to add more complexity and depth. Great work, this is a good, unique entry!
