Allegro Font Editor  
This is a very useful tool, and I've created a few bitmap fonts with it. It's easy to use. It misses a few features such as UNDO, keeping it from attaining perfection.

Molecule  
This is a very fun puzzle game... a good alternative to the plethora of Tetrises and the like you find everywhere. Nice, polished gameplay and presentation, just generally slick all around.

PeaceFighter  
I really liked playing this game during the Speedhack. It is technically a very slick, fun little shooter.

PixelShips  
This is a very slick little space shooter! Nice presentation, and has a very unique feel: good use of particles, interesting pacing within the levels (the level will stop scrolling periodically to fight a boss) lots of different ships to unlock, and a huge amount of missions. No sound. Worth a look!
