Would really like more features 2. More and cooler stuff to buy at the store. I feel like there isn’t enough rewards/incentive to go after a lot of the achievements 3 Just more things to do and more indicators ### 3/5 — Fun, but buggy *2026-06-13* Game is fun, but the achievements don’t work right. I stopped right on 10 seconds in blind mode and the numbers were in yellow and the prompt said “so close”, even though I got it exactly right. Took a screenshot just for proof. ### 4/5 — one bug *2026-05-31* When I stop it on exactly ten it doesn’t give me an achievement ## Frequently asked questions about On Time ### What is On Time - Timer Game?
