Hi Hrober,
There were supposed to be 1 or 2 other features introduced at the beginning before the dog but we didn't have time to implement them. So it ended up a bit long I guess. Sorry about that ! (u_u)
Also about WebGL version, we used some Post-Processing effects and if i remember right, WebGL doesn't support Post-Processing effects, or it requires some configurations maybe. I will have to look into it :)
Thanks for your feedback ! (>w<)b
