Long long time ago in the 90's I had a friend who was pretty exited about new programming language he had discovered. He told me it is pretty easy for person familiar with MSX-BASIC, but yet very powerfull. He did show me some of his experiments that were pretty much just maze on screen done with lines and then using paint routine to fill it. Practically all that I remember is that the paint routine delivered with the compiler looked like diamond as it was implemented in 45 degree angle. Therefore I had a bit hard time to get impressed due to pretty limited speed of the fill. Now I know better that the fill speed is not compilers fault. 
How ever this memory has been haunting me for quite a while as for few decades I could not figure out what the heck was that language he was talking about... Now I managed to track it down... It was TLX compiler 3.0 by Siropyon that he was using. The name TLX I believe comes from ASCII Tiny Language eXtended. Now my question is does this ring any bell for you?
Here is screenshot of sprite animation demo delivered with compiler:

... and here is how the main routine looks like:
begin COLORP(0);
SCREEN(5,3,1);COLOR(15,12,11);CLS;
PALETTE;BACK;GOODS;
X:=100;Y:=100;Z:=100;W:=0;
DX:=3;DY:=3;DZ:=0;
repeat BALL;STOPPER;sense;
X:=X+DX;Y:=Y+DY;DZ:=DZ+2;Z:=Z-DZ;
if Z lt 0 then {Z:= 0;DZ:=neg(DZ)};
if X >180 then {X:=180;DX:=neg(DX)};
if Y >145 then {Y:=145;DY:=neg(DY)};
if X < 20 then {X:= 20;DX:=neg(DX)};
if Y < 15 then {Y:= 15;DY:=neg(DY)}
until STRIG(1)
end.
Digging down the rabbit hole I was quite surprised to find some developer blog posts about TLX programming that were written more than 20 years after I saw the compiler! ( https://ameblo.jp/siropyon/theme-10065128316.html )
As this development environment has clearly quite some years behind already, I was wondering does anyone have any experiences or knowledge to share about the subject?
