It's really great but there is just a bug. when I leave the game and close it out it resets all of my data! I think is just a game and all that matters is that I know I beat the level. (But this bug might make some people mad.) So if my progress gets deleted then I still know that I beat the level. I think the bug only has happened to me I don't know why tho. (Sorry for my bad grammar I'm just a kid ;-;")
