Yep, I agree, I've been caught out on a number of workshop puzzles through the rewind feature not working. It's an annoying bug.
The concept behind the Escape Rooms was to fit the entire puzzle into one room, with the exit in the second room... which is why I only created a few of them.
Thanks for your comment.

Could be a decent puzzle. Unfortunately, the rewind feature of the game doesn't interact properly with the "cannon" devices, so a lot of the time you'll make a mistake and have to start over, making this extremely frustrating trial-and-error. Gets a thumbs-down for that reason. If there were a space to shuffle psychocobt back and forth then the rewind feature mgiht start working again, but I don't know for sure.

неплохая задумка
