Okay, the createprocess error may be caused by me, if it doesn't work for you, I'm sorry, there won't be a demo, after this demo was released I started redoing level 1 and it's in a very unfinished state and the old one is basically lost forever.
if anyone is having the error that ends with Createprocess ()
returned 2, it may have something to do with your firewall or antivirus software thinking the files are viruses since this game isn't commonly downloaded and deleting them, not 100% sure though
