Not bad
This isn't absolutely incredible, it's not terrible either, but needs some improvement. On one or two of the animations there were skips from places, but them being animated was actually a plus, I've never seen them animated in a scene creator. The screen to put your sprites in was really small though, but it's ok. There is a huge sprite collection, they're all animated, but they still look a little shawdy, but it's a good idea.
