Hey, I was gameplay programmer on this game. Rating it 5 stars because I love it! It's local multiplayer, but works well online using Parsec. I can feel stuff missing, but we might just complete it even if it was for a gamejam. Then, it will be truly wonderful.
If you cannot accept "learning to use a gamepad" as valid challenge, this game is not for you though. It has absolute controls (as opposed to relative), commonly known as "Tank controls"; I prefer the term "Remote car controls". Anyway, grab a friend, grab Parsec, play online, have fun!
