This game doesn't work as advertised; looking at the code it expects the screen to be 80 characters wide. That wasn't true on the 40 column Apple IIe unless you had the extra 80 column text expansion card. If you have one (and many emulators do) you can usually turn it on by typing PR#3 at the command line before running the program. That's not been done on the linked internet archive emulator (I'm pretty sure this isn't just me - all the screenshots attached to the internet archive emulation show the screen size is incorrect), but if you load it in another emulator like https://apple2ts.com/ that command is enough to make the game display correctly.
