Starting battles
The whole point of the game is to battle against each other, speedrunning through a level finding the best possible tricks to achieve faster and faster times. Therefore we need levels, plenty of them.
On a regular day, over thirty battles are played in Belma, so everyone is welcome to make levels. However, there is a certain Level Designing Etiquette in Belma!
startballe.exe
With this executable you can start a battle. There might be a battle on, but don't worry, there is a queue (Max one level per user allowed in the queue).
If something happens to go wrong, you can ask moderators to abort your battle. Wisest is to say it when your level is in queue, if possible.
Before you start a battle
Always be careful about the level you are starting. Test the level to make sure all jumps etc. are possible and all apples reachable. Make sure you put the start object back in its place after testing. Don't forget any apples or killers. Make sure there aren't any hangs or rollercoasters with too narrow parts.
The moderators can easily get annoyed if you start a regular battle on Internal 1: Warm Up! Starting internal battles is not recommended most of the time. However if there have been no battles for ten minutes or longer period of time, an internal battle could be fine.
There are many types of battles that you can start. The most common and favoured battle is a regular hidden (See others unchecked) battle on an external level. But there are many more battle types.
Never start a battle on an old level, this is the most important thing about starting battles. The whole point is that nobody knows the level beforehand.
