It's a common result, both in game jams and on itch in general. The more difficult it is to do something, the fewer people will do it, even when the 'difficulty' in question amounts to a few more clicks. I definitely opt for browser based entries over download only ones even though I'd prefer for people to play the download version of mine when possible. Likewise I keep the browser version of mine up despite it having a nasty bug I can't find a way to fix, because there are still far more people who will play it as a result.
