Increases the tick rate of Minecraft by 1 every 4,000 ticks (200 seconds), including the rate of change itself. So at 40 TPS, it's every 100 seconds, and so on. Can you beat Minecraft before it's too fast?
This data pack MUST BE INSTALLED ON A SERVER (in the world/datapacks folder), and you have to change function-permission-level in server.properties to 3. This is because the /tick command requires permission level 3, which data pack functions don't normally have.
To start, run /function tickspeed:start.
Tick speed resets whenever the world is reloaded.
