If it doesnt work in the browser dont release it in the browser as it was unplayable
When started it is very large but cut off at top and bottom but not obvious this was so. I also couldnt seem to set anything anywhere (one fungi) and no baddies happened so no idea what was going on.
I suggest making the size smaller say 980 x 600 so its easier to see the full screen button where it did work better though I still got a big 'javascript' error at some stage (twice now when I used the hot dog).
