I know i'm not imagining this, there was a game i used to play on our old BBC computer at school i have no idea what it was called, but i get the feeling i'd know the name if i heard it.
i remember a boot (or it may have been a shoe) with a wheel attached to the heel to propel it along. you had to work your way round the screen, ploughing your way through loads of colourful objects, picking things up along the way, The music was really twee and cheesy, as with many games from that era.
