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?
How can people support our Game Jam games after submission?

I uploaded some MP3 audio files into the game. After i created executable i have ~10MB because GameMaker creates OGG of the music and store MP3 versions also. Can i delete MP3 files and leave OGGs only or it will break the music at some point? Thx
