very stylish, and the core concept is fun. i liked all the character designs and bosses. the art is ace.
for my taste, the game was too easy even on hard mode, and it seems to just get easier since the game doesn't ramp quickly enough to keep up with the player's upgrades. it's certainly a tough thing to balance. i love playing bullet hells like Ikaruga so not sure if i'm in the target demographic or not. i might be the only one complaining about easy difficulty so don't change it for my sake :)
good job!
