You repurposed the Sega materials very nicely. Keep at it!
No original designs, audio or theme inevitably led to a dry flash. Aside from that, it was also short, a bit cringy with the strange pause in sonics lines and didn't provide any form of emotional reaction with the pointless story. Take what you've learned through creating this and give it another go! Trying and failing is still head and shoulders over never trying at all.
