I love a good bullet hell, and I love this! This is very good! I did run into a few problems, though:
- I ran into two crashes. First of all: pressing "R" in any context crashes the game. No idea why. Second of all, when I died pressing the Return To Main Menu button also crashes the game. Perhaps this is a WebGL issue, as I know you were struggling with that, but it's weird nontheless.
- Often times I would get completely trapped in a corner cause of how the enemies spawned, and was incapable of freeing myself. Perhaps this is intentional? But it did feel a little unfair.
Some positives: I really liked the music and sound design! Feels very crisp to play because of it.
Thanks for creating!
