Well this game was pretty fun and even more with this bug
It seems that the spinning attack of boarrior can push you outside of the map
I know this is pretty common in the normal mode game, but I place this post just in case someone can fix this (or avoiding using move displacement attacks in future events...just saying XD)
Thanks for listen
