It's a WebGL build? Please, can you add a Unity version so I can play on XP?
Thanks for taking the time to check out the game! Unfortunetly, it's built on Pico-8 ( http://www.lexaloffle.com/pico-8.php ) with no plans to port to Unity, sorry. However, if you buy the Pico-8 console you should be able to play it (and many other amazing games)! Could be a great investment if you are running an older PC as Pico-8 has very low system requirements.
