I don’t normally do this, but for family (and a good game) I will. My uncle Dave has a game on his site called RetroBlast that is very good. For those of you who weren’t aware, my uncle did a bunch of games for the Atari 8-bit and ST back in the day. If you liked what he did back then, you have to check out his latest game.
BTW, on a downside (at least for me), it’s currently Windows only. Hopefully that won’t last too long, though… 🙂
