Blocker  
It's OK software, but not terribly exciting. Also, the graphics could be a little better. You should consider making the whole game free too.

Gismo  
It's a pretty wierd game, but I liked it. It's quite fun to play. The graphics aren't the best, and some of the tutorial was a bit dull, but nobody watches the tutorials anyway ;-)

Magic Bubbles  
Great, and I like the hand drawn effects, very nice.

Outer-Rim Pod Digger  
Unfortunately it made my PC screen go funny and then crashed :( but on a more reasonable computer than mine it'd run better and the graphics do look cool. Besides, anything which can be made to run on a Mac must be good :) But can't it be 100% free?

Space Invaders Clone (1978 Midway Arcade Version)  
It's a pretty good old classic, and just as tricky as the origional. I liked it quite a bit.

Super Monster Painter Extreme  
Is this the best program ever? I think it may just be!

WormHole  
This is actually pretty cool! I wasn't expecting it to be but now it's my screensaver and it looks coool!

Worminator  
I love this game, from the over-the-top guns right down to that great music... it's great!

Zombiepox  
Yet another good offering from Free Lunch Design, though you may question where he got that big box of brains....
