Hey HogePiyo,
this looks like really great work. Had no luck running it so far, though.
The Visual C++ Runtime Library you inculded in the download claims that a certain *.dll is missing, so i downloaded a slightly larger runtime with the same name directly from microsoft ( 8.2 mbyte ).
But then the physics model editor refuses to start by complaining that: "This application has failed to start because the application configuration is incorrect. Reinstlling may fix this problem"
System: WinXP professional version 2002
Any idea how to solve this perhaps?
And from what i see on the screenshots: looks quite promising. keep up the great work :)
