Hm, this shouldn't happen and nothing has changed regarding the mouse controls. Are you sure this happens only in 1.4.0 and not in 1.3.0? It seems unlikely that this is due to the update of the game.

You can use the original page, I'd recommend keeping the original file up though and calling it the "jam version" or similar so people can check the difference between the jam version and updated one.
I'm not sure if this is still possible (Itch.io might have locked it) but edit your game and on the bottom you should set it to 'public'. If that's not possible anymore then I'm afraid you didn't make it in time.
That makes sense! Thanks for the throughout answer, I was simply a bit worried because it can have terrible consequences if it wasn't in your right to distribute these but this all seems perfectly fine. Thanks!
