I'm glad you like it! Sorry about the bullet sorting layer...
Yeah, that upgrade bug is really annoying. I found the bug several hours before the deadline and I somehow couldn't find what caused it. Two days later, I found that it is because of the distance between the UI and the camera. If we get really technical, my UI is 1000 units away from the camera and the torch collider blocks it from firing. It is a simple fix, but one bug I learned on this jam.
Thank you for your feedback!
