    Are there any errors in the editor after building the game?
    seems that the conversion system didn't run for some reason

    sorry -- perhaps I missed a step -- Play in editor is not supported?

    Correct, currently Play in editor is not supported with Project Tiny.
    We advice you to test any modifications by creating and running a Project Tiny executable.

    I dont see how you could develop a game if you have to wait 5 minutes for each modification, regardless of size?

    Use dotnet builds for iteration
    the first time you build it takes time because we cache the runtime assemblies but for iteration, they shouldn't take 5 minutes
