I found the game on a site for retro-games, and I can play it with DOS-BOX emulation. However, for some reason the game is very laggy for me. I'm not sure if the problem is in the game, the emulator, or something else.

I did my runs in DOSBox at 15000 cycles. That felt very playable and I don't recall encountering any lag.

Raising the cpu cycles from 3000 to 15000 did the trick. Thank you!
