This was a really cool game! I loved the way the ships fly in and out. The first boss was epic, really wanted to see the next one(s). Unfortunately i'm playing on a Mac and the ctrl + arrow keys scheme isn't too mac friendly, it causes the screen to switch to another desktop and the game also pauses. Hard to know that in advance, but just offering some feedback for the small audience on Macs like me. Great submission to the jam, nice work!!
