Eh...
Not bad. I have sound effects, if you give me your email. PM me. About the flash. Obvious stuff. Needs sound (you obviously know that), The movement of the sprites needs some work. And also, You really have to watch your style mixing. It is extremely annoying to see bad style mixing. Try not to do it so much. Although, it looks like you've already got most of your series done, judging by how fast these are coming out. Anyway, always room to improve. I have a number of sounds. Do you have plans for sonic characters? Those Mecha Sonics seemed to scream "SONIC IS COMING!" Anyway, yeah.
