Beat it in 09:41!
Really enjoyed neat details like pausing the game while showing Morgans life gauge refilled. Didn't really like Rapid Fire at first but then I noticed it disassembles Morgan like crazy. But I could only beat the Ancient Guardian with a Shotgun because it's the only way I can actually concentrate on micro-dodging and still deal some damage :)
As for the dash cursor, it would've been great if it was rendered in-game. Would make it a bit more intuitive, and my black mouse pointer won't be blending with the blackness of space as much.
I also took a peek at your source code. I found some stuff really neat, like the procedural drawing for projectiles, and the wavy background shader. And the way you do your state management and transitions with timers seems like something healthier than what I attempted with function pointers and coroutines in my project, lol.
Also, the music totally slaps. All the tracks are such bangers.
