Not sure you are aware, but there is an opensource version.
I did some updates on my fork: https://github.com/xesf/jc_reborn

There's also on older attempted to make it using JS: https://github.com/xesf/castaway

Would love to see those.

There's a lot of LBA2 fan art, but not many or none for Time Commando

Not in this build I am afraid.

Try different browsers.
Depending on the OS you are using, some browsers work better then others.
Usually FireFox is the one with stage 60fps.
