Hey!! Thank you A TON for your comments, I can see your BIG enthusiasm for this game and its origins, I'm happy I'm not the only one! :)
You know, I was SO SURE it was "TI99-4/A" that I was ready to say "oh no, you got it wrong", BUT... I looked it up, and I stand very humbly corrected, so thank you so so much for that! Now I'll always think of this next time I'm going to mention the TI-99! :D
Of course now I want to see your Extended BASIC version (I used that too, a lot, back in the day!), as well as your future "modern-retro" remake!
Some guy on Facebook who saw my version also suggested to put more than a Monster in the game, but I was really exhausted and wanted to move to something else: I had been working on this, in my spare time, for about 4 months! :) Still, I'm really curious to see the kind of impact that has on the game!
Yeah, XC=BASIC is surprisingly fast, to me at least!
Did you see my source code of this? XC=BASIC is pretty similar to Microsoft QuickBASIC regarding the syntax, so you shouldn't have too much trouble understanding what I did :)
