Post here your demos and examples with the source files.
Forum rules
Always post the games with a screenshot. The file must have the ged and data files (complete game source) Use the forum attachment to post the files. It is always better to use the first post to put the game files
Anyway I also dont know, if I edit something and then run the game, the game will be shaked... I avoid it by exit the GE, reopen the game, and then run it without edit anything.
