The engines themselves are over the 1.44mb limit, but the games are smaller... is that fine? I know it's semantics, but I'm rather new with a lot of coding languages.

Yes. As long as the game is smaller. One of the submissions is made with Pico 8 and is 1.24MB.

As a note for anyone considering this, pico8 executables can easily be over the limit, but from my tests exporting to html has always gone under 1.44mb. So do that.

Yeah, only html. Executables are over 1.44MB

Awesome! Thanks for the heads up, everybody!
