Great "game" you made there, but...
1. Either it's Wine or GameMaker that's scaling your game "linear", not "nearest". If possible (AFAIK in GameMaker 6 you were able to do it by double-clicking on one of the bottommost menu items on the left... or so and then navigating thru the menus), change it.
2. Other than that, it really is lacking gameplay. No matter what I've pressed, nothing happened (except that I passed the main menu). I guess it's Wine so an NA for gameplay and audio (Wine still has got problems with GameMaker audio).
3. Unfournately, Ludum Dare isn't Imaginem Dare (or whatever would be IMAGE in latin), but still, I could give you full 5 stars for the art.
Other than the gameplay and audio and controlls and other missing stuff, it's really great for just two hours. Hopefully you will complete it somewhen in the future.
I can't really vote because I didn't make an game this LD.
