I asked webmaster @ mozilla.org where to send feedback/bug reports about
the game and had this reply:-

I guess it's best to go through their GitHub pages for that:

I guess the problem there might be the OS/2 Warp build. I'm not
completely sure, but it might be that it doesn't have JavaScript
Just-In-Time compiling (JIT) activated, and without that, any modern web
app will consume a lot of CPU, esp those that run a lot of code like
such games do.
You should ask the guys doing the (unofficial) OS/2 versions if this is
the case - apart from that, SeaMonkey 2.6 has a couple of know security
problems and you should update to a 2.8 version if possible.

For the actual game play problem, I think you can create an "issue" on
those GitHub pages.

I guess the above raises the question: Is JIT activated in mozilla OS/2
builds?
