Hello, in the main page it asks that it should be preferably work in browser - however, I'm having problems with my engine (Unity) and everything html isn't coming out...

So, what I'm asking is: Can I participate sending  my project as a .exe downlodable file instead?

Yes. It was just a tip. If you decide to compile the game in the format .exe, then I recommend to compress the file in .zip, so that the download takes little time.
