Space Impact on the Nokia 3310: heh I didn't realize Nokias had games beyond "Snake". Kind of cool, where they obviously have some processor/memory resources earlier phones didn't (not to mention the influence of later arcade games) but still super low-rez and bad sound. It reminds me of big pixel stuff on the TRS-80s.
I've always been interested in one-button games, Nick B sent me tapsnake (reminds me a little of my old game snakedrive)
