The game is fun, feels good to play. But the rules are a bit hard to understand. If it had a good onboarding, it would be a great game.
First it takes some time to understand that you need to time travel with those chips (only number changes, so it's a bit hard to understand something changed), then you need to figure out you can take chips between seconds, and only after that you should understand what do you need to do to win.
Sure, rules are on the game page, but I feel like for a puzzle game it's an important task to set the expectations.
