Woah, you're gonna put this game on rewritable disks? MY SON... You take after me. I've been thinking of doing that with my games for years.
Believe it or not, my favourite part of this actual game itself is the graphics. There's just something about the low detail-level and that ground. Outside of the graphics you don't get much game-to-player feedback when playing Pengo, regarding what you're actually doing when you play it. For example, when you beat a level, things reset and change so suddenly that it feels almost like you didn't advance at all. Even just a few sound effects to give responses to the player's actions could have gone a long way.
