Let me look into it and get back to you. I don't currently support that system.
I tried Farmageddon again,
but nothing happens in the browser game window.
Not even an error message.
The same with Neko Rhythm.
In "Go Go Star Blasters!!" I have a "Run Game" button
but the game does not start.
Zompocalypse and HEARTSLINGERS work.
In my opinion, Internet browsers are not for gaming.
