I wasn't able to test this out with multiplayer, but the single player seemed pretty solid.
I'm not sure what all of the power-ups do. The cans give you energy, but I wasn't sure if I really needed energy. I had no idea what the wheels do, I thought maybe repairs? But, after being hit by several cars and taking no damage I guess that isn't the case. The shoes give me a speed boost and I understood that.
There is a lot of clutter in the levels, which I think is fine if the camera zooms out a bit.. But it definitely made it difficult to feel like I was reaching any considerable speed.
I think the art is really good, and reminds me of Zombies Ate Our Neighbors. Lots of detail in the environments and subtle touches on the chairs! The music is also a good pick.
I did have some issues with my controller not registering for selecting characters, and a few menu selection choices. Cool concept! I used to have chair races in a warehouse, so this is certainly a real thing that people would do.
