Fui tentar abrir seu jogo e deu erro de versão, estou usando Windows 8.1, 32 bits
Managed to update the project's Unity Build to an older, LTS version. I also built a new version to just play in the browser. Hopefully that solves your issue?
I only made it a downloadable because I was struggling to get a Web Build working. Glad I managed to at least resolve my issue!
But please let me know if it still isn't working for you.
