Amazing presentation and music !
Feels really polished, the sprites have an awesome design to them, the music is a total banger, and i like the "battle the kaiju at sea before they reach the city... again" theme ^^ overall the game feels quite solid already as is
The difficulty is kinda insane, i kept dying so often that if this were an actual arcade machine you'd be swimming in quarters (more likely i couldn't really affoard the amount of credits i used XD) so i'm thankful you made them unlimited for the jam
But i still had a good time though, and i also like you went out of your way to make the actual aspect ratio of a vertical shmup it's a nice touch.
One small issue i encountered (but i think it's probably cause of the jam's time) is that when you choose no on the continue screen the game seems to freeze,
and i think i had a bug but it only happened once so i'm not sure what caused it, when reaching the frog boss, after beating him(while dying often) the game kept running and could move and shoot, but it didn't continue to the cat boss.
Other than these, its a cool game, good job to your whole team :)
