Pretty solid co-op SHmUP! Great job for pulling this off within 2 weeks!
So I played it with a friend, and we both agree. Good balance, no problem, all fun! We often split during the stages to take care of each side.
I think the art's quite good, especially Mai and Yuki's portraits - and unexpectedly good animations for the player sprites and the boss sprites. The stage BGM is a banger too!
My friend's brings up that the player shots could be more distinct from eachother, but the game's still quite enjoyable.
I recorded the game for those who may not be able to play the game right now, whatever the reason.
