Yeah. This one saves your data which is a good thing. I tried doing all the quests possible and just exploring a lot, attempting to beat the foes, etc. I really want the full game >.< that's probably why I've spent so much time playing their demos, cause they're so fun xPThat is a LOT of time ! Did you notice some demos erase your data while others save it?
Sonic Dark World is the only example I know of that saved your data after closing...
