Probably wouldn't take much time to re-make, but I figure if it can be saved, then why take it?
Thanks man, you saved a lot of my time!! ^^ I will include those on the next release, but I'm not rebuilding the installer or uploading fixes until the next release.
This is what I'm working on at the moment:
1) a new level editor which will allow the editing of the stage's sky (background and stars colors)
2) checkerboard textures have been removed, they can be generated procedurally by specifing the 2 colors
3) optimizing the game for multicore architectures
4) double-click on a stage file from the Resource Explorer will run the game and play the selected stage.
These things are almost done, and I could upload a new release in a few days. Anyway I'm really busy with university at the moment and I don't know exactly when I'll do it
