The rules refer only to “an original game”. A collection of games (published as a single submission) makes perfect sense if you consider them part of a unique project, a sort of concept album but with games instead of songs. If it’s just a way to bend the rules, I’d say it doesn’t make much sense.
I didn’t want to dampen your enthusiasm. Publish as many games as you want and then choose the best one to submit it to the jam! You can link the others here, so we’ll go read and play them anyway.
