I got stuck on a level because my ship stopped moving. At first, I thought it was my keyboard but it wasn't. I think it's a bug or "something". I restarted the level and I thought the bug is gone because I could control my ship again, but when my ship started to turn into rainbow, it stopped shooting and moving.
I got the "Collect 20 souls = invulnerable" upgrade. I also have the "Collector Drone" which automatically collects loots. And the last upgrade that I purchased before this glitch/bug happened was the "Random Weapon".

It's a strange thing to have that particular font and layout.
