We didn't think a retry option would be needed since you can just remove all the placed pieces quite fast. But will keep that in mind in the future
I think I didn't understand how to remove all the pieces inside the level, but if you can and that's my bad, then I'd say it's okay!
It's just RMB, and it removes pieces (both machines and belts) as you drag. So you can with a few swipes clear the whole board usually. But yeah, a dedicated reset button would be handy, and also not hard to do
