Hi - I've started your game and have a first look around - it seems quite nice :-) - and I'll surely try to finish it
I'll be glad if you want to try my engine for the porting - and, if you're not at all in a rush, I could give it a pre-check (so at least to start it) if you don't mind sharing your code (did you use directly C# or a more specific script language, played by Unity?)
Anyway - you did a great work :)
