Left side without CircuitBreaker, right side with CB
It is possible to see that right side is faster, even using loopback (which is faster than regular connections)
Another effect is that smooth is better on right side (no spaces appear between enemies)
It is not possible to see bombs being launched because bombs microservice were removed to trigger timeout
