I'd like to create a sidescroller demo based on this demo. I'm hoping to add a few more features and get it posted later this week. I'd like some input on what features you'd like to see. Feel free to comment on this post or use the forum.

Edit: I didn't have much time earlier when writing the post, but I'd like to elaborate on this:

Pixel movement is often incorrectly dismissed as being one of the many things that BYOND can't handle. Not only can BYOND handle it, it can be very simple too.

BYOND's default movement system lets developers focus on the gameplay and less on the game's engine. My goal is to create an alternative movement system with the same purpose in mind. By giving people a starting point for creating a sidescroller they can develop fun and interesting games and add some variety to what BYOND offers.

The engine behind the NES Mario Bros. games is not much different from Mega Man or Metroid. Sure, some characters jump higher, run faster, can morph into a ball, and have different types of attacks, but these are relatively minor details. By providing the basis for developing a sidescroller people can expand it by adding these smaller details and create many types of games.
