The Halting Solution

The year is 21XX. Your village has been growing colder over the years, with no signs of stopping. As a first attempt at fighting the cold, the villagers choose YOU to manipulate derelict computers that have been gathered up, to make their processors enter an infinite execution loop. This heats up the CPU, and with it, a home.

The computers are a bit old and broken, so their interfaces often have limited keys you can input...

[-----------------------------------]

The Halting Solution is a programming puzzle game where your goal is to make a Brainf*** program loop infinitely. 
There are 9 levels, an interactive tutorial, and a sandbox.

(Brainf*** is censored in all instances, to be safe, as the jam rules say to avoid strong language)

The browser version is the most tested version, and is stable and performant. Only in the case your browser doesn't support it do I recommend the Windows/Linux downloads.

Source code is available here!

TIPS IF YOU'RE STUCK

(If you aren't stuck, you probably shouldn't read these.)

- You can play the levels in any order (but I tried to order them by difficulty), so if you're stuck on one, you can switch by going to the levels menu

- Experimentation in the sandbox (or copying a level there) could be very useful!

- Slots can only be from 0-255, meaning going below 0 makes it 255, and going above 255 makes it 0. The last one can be a problem as it can end a loop []. Is there a way to skip 0?

- Trying to move the selected slot left of the first slot will do nothing - same with moving the slot right of the last slot. Could this be useful?
