I loved this game! I'm a big shmup fan. This was recommended to me in Twitch chat to try, we all loved the tunes, the visuals and the gameplay.
I think that the dash/jump/i-frame movement could have a bit more clarity, as well as the boundaries of the field, I didn't have a problem with it, but I know others did.
A kind of 'super ability' or just an attack speed increase could be cool too.
Super sick stuff! Would love to play a more fleshed out version.
