the arrow on the unicorn will tell you his next move if it is red and is down he will attack down if it is red and is up he will attack up and same thing for blue but for blue it means dodges the arrow on your head is your next move dont get hit and hit the unicorn also the unicorn has a chance of dodging your attacks even though you land them correctly(not me making up an excuse for a bug)
can be a bit buggy with the arrow colors report the numerous bugs in the comments
