well spawning instances wasn't the problem. The problem was that was all there was to the game. I think something didn't trigger properly. Did you test the windows build?
Oh! Sorry, there's nothing more, I'm afraid. It was the result learning Unity's animation and tilemap systems. I've sadly abandoned the project.
I should update the description, to reflect that!
If you want to. Don't be afraid to start over. Experiment! :D
