Not bad overall.
It's a good set of mini-games, but I have a couple complaints:
In Brick Slayer, once you get "Uber Brix" the game basically plays itself for a minute or so. It would be more interesting to replace them with score multipliers or extra time pickups.
All the action in Space Surfer happened outside the vortex. That may or may not be intentional but to me it doesn't make sense.
Fairy Fighter was kind of boring to set up, but interesting to watch. A "Randomize" button in the fairy setup box would have broken up the monotony.
Vey nice particle effects! You could definitely make an interesting firework simulation that could be added to a movie or something. I just wish they didn't bog my system down as much as they do. (Low quality works fine but there's no anti-aliasing. :C
