P.P.P.S. You can heal standing on the basin at the very start
P.P.S. So, shadows are also screwed up because of the compression R.I.P;
Try using a different browser; i asked a friend of mine to test it, and it worked, besides problems with game compression;
P.S. After you have explored the entire location you leave through basin at the start
Unfortunately, it appears that fire textures screwed up when i was compressing game in order for it to run via browser\
