It's cool but I wonder why would anyone want to write C# instead of Lua for the same API access ?
I mean, if C# could be native instead of translation into Lua, directly connected to Defold Engine via a C++/C# bridge, then this could be more meaningful.
I like your color tone and atmosphere, but you may consider upgrading the fidentity of the game, it's a bit low-res that affect the readable attribute of the game.
