Thanks for playing.
In the red world, once you kill everything, there is a bunch of debris that you have to push around (projectile impacts will nudge it) and move around to find an opening. Alternatively you can try to kill it before there is a bunch of debris blocking. I originally made it invincible until you killed everything else and had a much higher health bar and bombs but I toned it down a little.
The color and music are intentionally uneasy but we could also tune it down a notch. I’ll look into adding an option to disable or limit the particle effects.
