Close enough to the real solution, I don't think I can fix it anymore though

Another one? https://youtu.be/gAC6A7LYCbI

I'm afraid I was able to reach the exit even more simply than the first time: https://youtu.be/xgUROzlFiu0
If you have a lot of surfaces that you don't want gel on and are using a modern BEE2 version, the Surface Lacquer item might help?

Oh wow that is not at all intended. As for the signage, I did not notice that they used the same symbol lol, thanks for pointing it out, I'll be sure to fix it.

Nice puzzle! I was a bit irritated while trying to find the correct way to get conversion gel where it needed to go, but once I stopped and thought for a bit I was able to deduce I nice, clean method. I assume this is intended: https://youtu.be/ivndXjoKtEY

I was going to point out the alternate cube retrieval and the suspicious blue-gel proximity to the ledge, but it looks like hub beat me to it, haha. The fact that both the exit door and the autoportal use the same square signage was a rather strange.

The music was neat! I enjoyed it.

There are at least 2 ways to get the cube.
A bit illegal, but https://youtu.be/0lGYpfBUCnY
