Came back to this bug, and it still exists. Here’s a gif of me doing the glitch:
(code is invalid btw)
Notice how I stay in the same spot after the respawn, the quantum portal hit me, but is still on screen, and the clouds stop moving. The game is still going on though, because you can see in the KO feed when I get KOed by the sentry even when the screen is frozen. I didn’t include it in the gif, otherwise it would be too big to upload.
