I've found a collection of my old games in KNP. I can't even run them so I'm passing the savings on to you.

ASG: Crap shooter, choose individual levels to play. Space shoots, ctrl selects upgrade, / is a cheat to get more money.
BBALL: A terrible attempt at adding scrolling to KNP that crashes on level 2. Arrows.
BOUNCY: I'm quite proud of this platformer! Two complete worlds with boss fights.
COSMO: Full game. Enjoy the scrolling world and sound effects entirely sourced from early internet.
JOY: Oh, the first chinchilla we had. A puzzle platformer of sorts.
PACMANIA: Everyone loves Pac-Man, right? So have 15 levels of it.
S&S: The first level of this works pretty well and it'd work even better if there was a freaking MAP.
