pulse is a well-received, fast, horizontally smooth-scrolling shoot-'em-up I wrote for the unexpanded Commodore VIC-20. Download the program file here. You can get the source on Github. There's also a video of the thing on real hardware; thanks, Mike! Pulse is being discussed at VIC-20 denial. Robert Hurst has set up the pulse highscore table and a download page with quite a review. I'm SO out of words here. I won't mind your upvote on pouet.net. 0:)
