Play it at the Internet Archive
Version 2.0 was sold on floppy disks, not given away like version 1. Its help file says so in capitals: “This is a commercial product and only distributed as such. This is NOT shareware NOR freeware.” Out of respect for Attila Biro and Anders Moree, this site does not host it.
The Internet Archive keeps a copy and runs it in the browser. Click the power button on their page, wait for DOSBox to load, and you are in.
Play version 2.0 at archive.org ↗
In the game: cursor keys or joystick. Esc returns to the menu, Ctrl+Q quits instantly. Double mode: player 1 on W A D Z/X, player 2 on the cursor keys. Five worlds, and the baddies “stop playing around and start getting mean” once you get far.
If you are the rights holder and would like version 2.0 playable here, or would like the link removed, say so and it will happen.
