But I am making a collection now to put in my corner here.
All games are welcome whether inspired by the site or not. The more game code for others to learn from the better. I would be honored to have any code you would like to share.
@TerryRitchie
I would be honored as well if you use anything of mine you feel helpful to the cause. I will gladly make edits if you need things to fit better with your lessons.
All I need in the source code, any asset files (sounds, images, etc..), and quick explanation of the game and usage. A ZIP file would be perfect. You can either post it here in the forum or send the ZIP to my email: quickbasic64@gmail.com
Thank you for contributing 
Terry

I'm sorry for bringing up this topic almost two months after the last post LOL but it's fair for me to warn that I'm having trouble running this game on Spiral Linux. It might be today that I upgraded to Linux v6 kernel -- a first for Debian-based distro. Before that (with Linux v5.19.0 kernel) this program executed without problems. I tried to get fancy to get it to use a font other than the "system" one but it didn't work. I had been compiling and running the program as it was originally presented here.
Erm, an interruption to say... I really liked this game! More challenging because the alien missile "eats" the tank's, makes it harder when a few invaders remain. It's addictive because the user could press only one key. But that scheme falls apart because I want two-letter, not three-letter name on high scores list. But that's a childish request...
Anyway this might have to do with the kernel and other things. I should check this on the Arch-based distro installs that I have which have even newer point-point releases, the latest at this moment should be v6.0.10.
This is the error message I've been getting ("altonly" is what I named this program LOL):
Code: (Select All) [xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
altonly: ../../src/xcb_out.c:479: _xcb_out_flush_to: Assertion `XCB_SEQUENCE_COMPARE(request, <=, c->out.request)' failed.
Aborted
Sometimes the lines beginning with "[xcb]" aren't displayed. A window appears briefly, a mix of the desktop and any other window (usually the terminal) that might have been in its way, and then bumps back down to the terminal displaying the error.
c. 10 minutes later:
Switched to EndeavourOS. The program executed without problems without any change in the source code. However, something happened to the game after I killed all the aliens in the first round, and it stayed this way:

Hmm, not sure why it froze up. Those remaining bat wings might be a clue as to some infrequent bug.
As for the wanting to just include 2 initials, just replace the existing displayhighscores sub with this slightly modified one. I set a new inmax variable to "2" for two initials. See it near the top of the displayhighscores sub. You can also change the value from "2" to 1 or 3 for one or three initials.
Code: (Select All) SUB displayhighscores
inmax = 2 ' Change to 1, 2 or 3 determine how many initils you want to enter for high score.
IF inmax < 1 OR inmax > 3 THEN imax = 3
COLOR 0, 3
LOCATE 25, 68: PRINT "Score "; score$;
DIM hs AS STRING * 25
REDIM highscore$(6), hsdata$(6)
DO
IF _FILEEXISTS("ascii-invaders-high-score.dat") THEN
OPEN "ascii-invaders-high-score.dat" FOR RANDOM AS #1 LEN = 25
FOR i = 1 TO 5
GET #1, i, hs
highscore$(i) = MID$(hs, 10, 6): hsdata$(i) = hs
NEXT
CLOSE #1
ELSE
FOR i = 1 TO 5
hsdata$(i) = SPACE$(25)
NEXT
END IF
IF VAL(score$) > VAL(highscore$(5)) THEN
IF VAL(score$) > VAL(highscore$(1)) THEN
msg$ = " HIGH SCORE / Enter Your Initials! "
ELSE
msg$ = " Top 5 Score. Enter Your Initials! "

Thank you for this. I went further so the program accepted "2" or "3" at the command line, to be passed to the new subprogram.
