I'm not sure if it's just me but I can't seem to get it to work.
It doesn't work for me either (WebGL part).
Please try with the downloadable versions instead, the web build was having problems so I deleted it.
Cool, I tried the windows build and that worked. I thought it looked really cool! I did struggle to work out what I needed to do at the beginning. Nice Game.
Thank you! Perhaps reading the How to Play section would've helped.
