sounds interesting, by any chance do you do tutorials?
I will watch them to figure out what i did wrong.
or do you not have sonic sprite packs in it?
I don't know what you did wrong without taking a peek at your project. However keep in mind that tilengine is a graphics engine to program video game graphics with it, it doesn't provide any ready-made assets collection, only the assets used by the examples themselves. There isn't any sonic sprite pack, you have to build your own.
