Quite recently Unity Game Engine (not to be confused with Ubuntu's Unity user interface) added an option to create a linux build. The result is a set of two executable binary files .x86 and .x86-64, plus a folder with some resources. I have exported my Unity game and it runs great on my Ubuntu machine.
I would like to publish the game on the Ubuntu Store, but I have no idea how to do it, and if it is possible at all. The Ubuntu store tutorial instructs me to use Ubuntu SDK for packaging into "click app". When I run the SDK, it asks me what kind of project I want to create, with lots of project type options (QML App, HTML5 App, Web App, Plain C Application made with gmake etc), but I cannot see any way to simply package the existing executable binaries exported from Unity.
Could anyone help? My game (don't want to advertise here) would be a great and free asset in the Ubuntu store, to the benefit of the whole community :)
To clarify: I don't want to publish sources of my app; and of course I am not able to publish any sources of Unity Engine player. I simply want to publish my free app to the store, which I have as binary.
