I was also very impressed. I liked the overall feel of the game, the jumping, movement and hack/slash all felt appropriate. I liked how vertical the city got and how you can explore around. I stopped playing after landing the ship in the harbor. I'm not really a fan of the type of games where you go around and have to talk to everyone (even great games that use this like mass effect bore me after a while) so it was no fault of the game. It's got a very spyro meets basic RPG thing going on which again isn't my style but I could see kids especially enjoying it because of the graphics. If the game held your hand more and was actively making you do things instead of passively inviting you to do new things (collect quests) I would probably have played longer.
I filled out the survey but FIX THE COMMENTS FIELD in it. You can only fit like a dozen words. I had to come back to mapcore to write kind of informative review. Also in the survey I found myself checking a box but having a lot of if/but reservations about what I chose, for example the how much would you pay question. If it was a full game with a developed story at 5 hrs I would expect over $20 . If it was more of a 5 hours worth of mini games game I would expect more in the $10-15 range.
