Level 8 looks like it may have been intended to be more difficult than it is? I didn't have to use the time travel mechanic at all. Then I got stuck on Level 11, seemingly missing something fundamental for that one. (Video of my session: https://www.twitch.tv/videos/1459292471)
It also took me a while to realize that you can only use the time travel mechanic when standing on pure white tiles.
Although this is easier to work with than time travel games that require you to count out moves or time to cooperate with a time-clone you'll create later, it doesn't feel like a time travel game to me because it doesn't have the requirement that there be a consistent timeline (meaning that for each time a player appears, the player must disappear in the same place in the future). It feels more like a game where you can arbitrarily spawn clones in certain locations, as long as you can reach those locations.
