I have no clue where you got/made the song but it's amazing!
The concept is fun (obviously, I made a similar game!). The shooting feels a tad bit random from the enemies tho and it makes shooting an enemy a bit of a lottery. I'm not sure what the solution for this would be but it makes me play really slowly shooting one by one enemy. However, I feel like the game looks coolest when you just go mad with shooting and trigger a bunch of spawns - I'd like to see you encourage that somehow.

I wrote the music during the jam using Reaper as my workstation. Here's a timestamped link to the music production.
