The grub-racing game made a lot more sense when (playing on a keyboard) I realised that the WASD controls were absolute, not relative.: W is north, not forward! I was playing alone, but didn't figure out how to win it. For all the games, I never really gathered what the occasional timed marked in the centre did.
It's basically several games of a similar theme collected as a suite, which would work for couch play if extended to that format.
