Thanks! I did not like how Godot plays audio (very weird bugs). The enemies not colliding with each other was a initial feature (so you could smash multiple enemies at once) but it would be better having them colliding indeed!
That's weird that you are having audio bugs in Godot I got mine to run just fine. I just use a sound manager that instances the sounds and when the sound is finished then destroy them. Not sure why the music only played on one channel.
