I started writing a jump'n'run game in Flash a while ago, using André Michelle's excellent gamepackage (sadly discontinued). Controls: use the cursor keys to walk, hold 'c' to run, use the space bar to jump.

Unfortunately, I'm not likely to finish this on my own any time soon, so if anybody out there is a capable Actionscript programmer and looking for a fun little project to help on in their spare time, drop me a line.
