Biggest regret was not building a web version and only a windows version. Seems like with so many games, being able to access them fast helped to prove player engagement. I ended up making a web build and linking it to the submissions page, but anyways, I'll do web focused for the next jam!
Same story here, mate. I was using Love2d and there was a possibility to make the web version, but I neglected it, providing just Windows and Linux builds. Now I think I most definitely should have the browser playable version. Still, you can play it on those two platforms, and the download size is tiny :)
