Operation: Stalwart Redemption - Week One, Take Two: Platform Runner

I've got a new idea for my first game, and it's quite a bit simpler than Py-Type.

The title of this game is "Platform Runner", and it is a throwback to the glory-days of old-timey IBM PCs, shareware, and 2-bit color palettes.

The game centers around a rather nondescript-looking woman named Stephanie who must make her way through levels of forbidding terrain and harsh bad guys to get to the exit door, which inevitably leads to more problems.
The game's terrain will consist of solid terrain (Solid ground and platforms) and ladders.
Stephanie will be able to jump about 1 1/2 tiles high and about 2 1/2 tiles wide. If she falls down more than two tile-lengths, she will die.
Stephanie will also die if a bad guy attacks her. She can defend herself, though. If she punches a bad guy, that bad guy is stunned for a few seconds.

The game will use procedural levels. There will be 25 level sets (Which are made by seeding the random number generator with a number from 1 to 25) and fully random levels (Which are made by seeding the random number generator with the current time).

I have a demo ready, though it's just Stephanie and some simple terrain.

You can pick up the demo here.
