If laser goes through gateway placed above a laser catcher, it will go through mirror, if time gateway is placed somewhere. Echo looks like it is not even holding any mirror.

I'm running the game on Linux, I don't know if bug's reproducible on other platforms.

Oh, also I don't hear in-game music. Music volume slider in options doesn't do anything.

Your two posts have prompted me to write a blog post on how some of the time travel coding stuff works that will explain these two issues in more detail. I will post a link on the "Gateways Editor" thread when it's done.

Huh, so I wasn't able to redirect beam because it was triggering the switch somewhere. I think placing gateways on switches should be prohibited :/

[SmudgedCat]

Yes, that's reason. It makes sense not to have them on switches. The current editor will automatically place metal beneath switches which should prevent this. This level was made with a previous version of the editor.

Sorry about that, it seemed like a good idea at the time :D
