I've been hard at work drawing the tile set for the first stage and finishing the map. Also, I have added a music and sound system, that seems to work to my satisfaction. While testing, I noticed a weird camera stutter, and realized this was due to the player having decimal speed. Given that I use a pixel perfect camera, this causes stutter. Also, the player moved a bit too fast, so I have adjusted the speed to an integer.
