Yeah I didn't realise that there was an issue until after the jam. This is my first time building  Unity game so in all honesty I had no clue. Next Jam I will make sure the game is playable

Thank you for telling me this, this is my first Unity build and I did it last minute and I thought just the .exe was ok.  Next jam I will make sure I do it correctly. Thanks again for telling me what exactly I did wrong.
