Great but needs to save levels – JVGS FREE - Stickman Running Game in a World of Dinosaurs & Time Travel! Review

I love this app!!! This is an AMAZING app!! All it needs is to save the levels you finished on. I got to about the 8th level, and then I got off. About half an hour later, I got back on it and nothing was saved. I had to redo it all the way up to where I finished. The next day, it was deleted again. I'm not sure if I should even use this app if nothing will be saved. ?
