Note: You should be competent enough to compile programs to get this to work. Since every system is different, I can not give instructions for every system. I can only just give you the program source and and let you run with it.
Step 1: What you need:
Source for the the mini adventure
Step 2: Freebasic
Note: There maybe some qbasic compiler for the Mac computer, but you will have to look for it.
Step 3: Download and compile the code.
2. From the command line issue the command:
fbc -lang qb gamadven.bas
3. After it compiles you can run gamadven and play the simple game. it is all keyboard controlled so there should be no problem playing it.
Step 4: Final words.
Watch for a web version that can be run on a server soon.
