All of my games are available to everyone for free.
However, if you enjoyed any of my games, a couple of bucks to cover website hosting costs and support my ongoing efforts would be gratefully appreciated. I think $2 per game enjoyed is a fair price. Thanks.

I heard a Focus Group convinced the Atari Lynx team to make the unit unnecessarily large, which meant that it was a long more awkward to carry then the far more compact Gameboy.
I'll write you soon.
