I think you should only have to do one picture puzzle because the second picture puzzle wastes your time. I also don't like how many glitches reflex has. It's also super easy to get to 100% facts fluent. So I think they should make it harder. To make it harder you could make it 2 times harder to get a fact fluent. Also the addition and subtraction version is way too easy the hardest equation is 10 + 10. The multiplication and division one should also go up to 13 x 13 and 169 13. The addition and subtraction should go up to 20 + 20 and 40 - 20.
