If a multiplayer-version of this could come someday, it would really be great, because especially this gameplay here of "Cabygame", is ideal to be played with more than one player at the same time.
Since there are now also 4-player-adapters available for the C64, one could even think about, offering a 4-player-simultaneous mode too in the game-menue, in addition to 1-player and 2-player simultaneous. I could imagine, that this would certainly be super fun as a party game, played with three friends, all sprites together on one screen against each other. :-)
