Pretty nifty stuff!
There are a couple issues, no resolution settings, mouse sens, or graphic settings, but this is a demo and functionality is the paramount.
I'd love to see this get made, I could see this being a nice and casual experience, though I'd love for the environment to get a lil more vertical and for the game to utilize the roller-skates more.
4.7/5!
Best of luck! Cheers!
