Yes, I know that as well. You can still download the game. I compiled it with QB64 3.2.1, but something doesn't work there. Will put it under programs.

Hi Steve
fine your version of GetScreenMode with new _QB64keywords....
_PaletteColor
_PixelSize

and the _MEM type of data assembled together with DATA into code. 
A fantastic example of how to mix old Qbasic and QB64!
Thanks for sharing it.

I have taken a look at it and it seems only the old Nibbles.bas
And it runs ok, only too fast.
We slow it into main loop of game in SUB Playnibbles  using a _LIMIT 10, maybe after the comment 'delay game

Nibbles.bas fixed and posted as code in your thread
