I've had years to think about this, but Nintendo mods being pulled from Garry's Mod's workshop lead to true enlightenment; that Tower Unite was a warning sign for what would happen to GMod’s legacy.
This game is disgusting. A deliberate sabotage of almost everything good about GMod. You will like the lack of copyrighted content, from Valve or elsewhere. You will like the Fanboy and Chum Chum ripoffs. And you will certainly like the inspiration from Roblox, not from the Source Engine's history.

I went into this game thinking "Okay, people say it's bad, though I see some potential with it and maybe I'll have a good time." But yep, it sure is Sonic Lost World, a 2013 platforming video game in the Sonic the Hedgehog franchise.
At least the music is really good...
