Hey, Xaklse. It's me again, Handepsilon. We exchanged e-mails about SonicGDK back then after my Trial in SonicRetro expired.
I just wish to tell you that I'm planning on re-researching the GDK's scripts for my team's UDK project, particularly the part that keeps Sonic aligned to the floor. I hope that would be ok with you. Thanks in advance ^^
No problem at all, best of luck.
This is awesome work, the physics are incredibly done. Thanks a ton for this.

Hello my friend. Congratulations, your game looks amazing, I will for sure try it! I am also a UDK developer (@udkultimate), and I want to invite you to take a look at my new upcoming game, made in UDK (a modified version which exports the game for PC, PS3 and Xbox360):
