just checked it. Honestly, you don't need to upload it as an engine while having the whole game hidden in there, i think you'd be better uploading the one level demo Obivanhelgen himself did, which is what i used as a basis to work on and learn how it all functions. It has a smaller size and a more concise structure. I have that build saved somewhere with the improvements i made. Let me just check and i'll give you a link. It's actually a one level demo that you can't find anywhere on the net right now, so you would say it is even "rare".
