Aura  
Original idea. I was thinking about doing a game for deaf people once. This guy beat me too it. Takes some getting use too. Interesting concept that for sure.

Icy Tower  
Version 1.2 makes an already great game even greater

Storm  
Something about the graphics gives me a nostalgic feeling of the good old Amiga days. The game is really fun and becomes quite a challenge on the later levels.
