Help in GameMaker

Hi, everybody! I just submitted my GX project. Does anyone know how to upload it so people can play in the browser? Also, is that mandatory for the Jam? I've only got a downloadable zip...
hey does anyone know what kind of app I need to make a game on? im kinda lost...
how to make 8 direction movement? game maker visual launguige is very unintuicial.
For the GX Jam: Are we allowed to use CC0 fonts? The rules do state that all visual elements need to be created during the jam, so I'm thinking no. If we can, does it state that anywhere?
For some reason my game over screen won't reset the game. I have in the game object step event:
if(keyboard_check_pressed(vk_enter)) {
switch(room) {
case rStart:
case rEnd:
room_goto(rGame);
break;
}
}
It works for start screen but not end.
