Bought the pro version of the app. However, lately the app has stopped allowing more than two layers and has been behaving as the free version of the app. There's also the problem of force closing and glitches in the saving process. I've had to redo a few comic clips for a current comic I'm creating due to the glitch in saving. Otherwise it is/ was worthy of a 4 star review. If the glitches in the owned version can be corrected, force close and save glitches fixed I'll re-review.
