I don’t know if you have heard but on Roblox, there is a gamemode called Meep City.
I find it like GMT or TU for some reason, except for noticeable stuff…
1: The Only Pets are Meeps.
2: The Music is the same Copyrighted music from Gmod Tower in that Ball Race Clone.
3: Customisable Avatars Like TU
4: House customisation from TU and GMT
5: In the ball race clone, you get infinite lives instead of 3
6: Ball Race is Called Star Ball
7: There is no time limit in Star Ball
8: The game is also Early Access
9: Unfortunately this does have micro transactions in the form of Robux.
10: They have fishing implemented unlike TU which is still being implemented
A lot more follows…
Maybe the guy who created this was a big Fan of Gmod Tower / Tower Unite / Toontown ?
