I made a few changes for the second revision. Many of them had to with the collision system, as I wanted it to be usable on all levels with minimal changes (the original was done with no regard for any type of scalability). A few graphical changes were made, too.
The biggest change was adding of the second level. It is still under construction and the animations should be ready tomorrow (I'm hoping) so it will look considerably cleaner. Once those are complete the collision and second enemy can be added. The plan is for the second level to take a few screens, with the next screen being part of the storytelling element. This is why the graphics are critical, because without them the theme of the game is lost.
