Similar to regular Brainfuck with the following changes:

• ] does not jump back to the start of its block
• ( starts a for-loop setting the loop-counter to the current cell If the current cell is negative, the loop-counter will be set to its absolute value and the roles of + and - will be swapped within the loop.
• ) decrements the loop counter, jumps back to the matching ) if the loop-counter is non-zero and the current cell is positive
