Sorry but I'm keen on it. Releasing it with the source code would allow user study and modification (assuming one's willing to install a C/C++ compiler for the latter purpose). I'm especially keen on it because 1) I'm really not a competent assembler programmer, 2) I'm fed up with writing assembly language -- far too time consuming, 3) GCC tends to generate better quality (more efficient) code than I can, 4) I like the idea of making a DLL-based graphics library. No one has to use it, and let's be realistic about this: hardly anyone -- and probably no-one -- will use it. For me, it's just a matter of hobby fulfillment. Frankly I don't give a toss if anyone uses it or not. Since I only intend to write assembler code if my life depends on it, I'll code speed-critical routines in C and get the compiler to generate a DLL or an assembly language dump (that hardly anyone would be able or want to study, understand and modify anyway).
This C/DLL stuff is mostly about me avoiding ASM coding!

I may take a look, thanks for the pointer (*).

There is no challenge if you use a DLL - you simply move as much code into the DLL as is necessary to allow the remaining program to fit. 
There's a nice Liberty BASIC version of PacMan which has been translated into BBC BASIC using LBB, although it won't fit in the trial version. I'll take a look to see if it could be shrunk enough to do so (it doesn't use any of LB's native graphics - everything's done using GDI32 API calls - so it doesn't need the LBLIB library).

Presumably any DLL you build could equally well be called from other programming languages - including Liberty BASIC and C itself. You might find a more receptive audience elsewhere.

I was referring to only the graphics library, not game logic.

Using LBB 2.53, the game translates and runs without complaint, except the window doesn't update. It's initially black (I can hear the sound effects), and it only updates after I've dragged the window around to force an update, but it still doesn't update automatically. I'm using Win7 / 64-bit.

If I was concerned about having a receptive audience for my solitary, hobbyist coding activites, I'd be using Python, Java (which I'm learning), DarkBASIC, Raspberry Pi, etc. Huge communities.

The program requires modification to be compatible with LBB (as many do). Run it in genuine Liberty BASIC if you want to try it.
