I made a demo version for the PC. You can download it here:www.lastguygames.com/sekrit/CurseOfTheCrescentIslePC.zip
It's about half the game and it'll bomb out once you finish that half. The requirements are: you must have Windows XP, Vista or Windows 7, a graphics card which supports DirectX 9.0c and at least Shader Model 1.1 and XNA Framework Redistributable 3.1 . I think the installer will also try to install xna if it's not already installed but I dunno.
Just extract the zip and run the setup.exe.
F - pick up enemy / Run / Advance Text
D - Grab
Up - Jump/Open Door
Arrow Keys - Move Around
ESC - Menu
Enter - Select Menu Item
I'd highly recommend using Joy2Key because playing a platformer with the keyboard is kinda balls.
If the installer bombs, the game bombs or the game runs slow, post the error message and your PC info and I'll see if I can figure it out. If the game installs correctly and runs but it tanks it'll generate a errorlog.txt in the same directory as the .exe.
Anyway, I'm putting this out there to get a feel for how difficult it will be to get the game running on PC.
