It's a bit glitchy, but not bad.
There are times when my mouse clicks don't work well. As if the replacement for my pointer is in one place but my actual pointer is in another place. If it was only a movie I wouldn't care, but it does make it impossible to dodge the bombs when I mouse and cursor don't sync up.
You should also make a level where you can run as sonic. That's my favorite part of sonic games. XD
