You are a new worker for a facility and you have been assigned a simple task: Setting the core temperature. You have been told one simple rule: "You may set the temperature to exactly 1000⁰, but do NOT set the temperature any higher than that!" Press the space bar to edit the core temperature after you have already set it. Also, the core shuts down if you try to set the temperature to anything which isn't a number.
I made this yesterday in the Scratch 1.4 editor and uploaded it (almost) unchanged, which is why it is very low quality.
