Ratings and reviews

its good but the movements are inverted for me, it tells me to turn the lock right but I have to turn it left in order for it to be correct

I don't like how it makes you reset if you make one mistake and you you have to pay to make a custom combo. like what if kids want to practice the actual locker combo.

I find it really helpful to get use to opening lockers but everything's behind a pay wall of 1:99
