the game is a bit buggy when moving back in time, then forward again, etc. a lot of collisions and invalid states can happen which makes it difficult to play. nevertheless, it's a cool idea and the multiplayer is impressive. good job!

Better feedback on invalid moves is actually something I was working on during the bonus bugfix hour, and I missed out on submitting it by about a minute, so I can only apologise. I hope it was still some fun for you anyway, and thanks!
If you did spot any invalid moves being allowed, or legal moves being banned, please do let me know.
