I checked out Fires in Funtown recently by another one of the regulars on the Penny-Arcade Games and Technology forum.

It has excellent music and a really neat art style, so I dropped the creator a note on how much I enjoyed it. While discussing the game, he mentioned that he codes his 2D games in Flash and recommends it as an engine. I will definitely add it to the list of environments that I check out once I complete the Game Maker’s Apprentice.
His site, Fat Badger Games, also has a really cool looking upcoming game called Blobulous in the Kingdom of Blobonia:

It’s really exciting to see a lot of the cool indie games that are coming up. I hope my games end up having half the charm and style as those.
