Help in GameMaker

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.
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
Ok gotta ask something about Tech Over, i have been trying to add both a modern and retro mode, retro mode is hard mode, modern is normal, i have slowly noticed this is a bit too ambitious, so should i remove one of the modes or keep going with it?
So, I'm dealing with a problem when building my game. The game runs fine when I run it in test mode, but whenever I set the target to a browser, the website does launch and open the game, but it gets stuck on the first frame and remains as a still image
Hi all. My GM is acting weird. I deleted a sprite & now everytime i open GM it says Warning & sprite is referenced (It's not) & says another newly created sprite doesnt exist (not set before reading) when i try to use it in game. Any ideas? Thx!
