Super cool prototype ! 
I liked the fact that we have to take some damage or to teleport first to be able to slash ennemies ! The only thing that lost me was the fact that I couldn't see the teleport limits ( the red limitation of the fight-area) but that's all :)

I did well and ended with the victory screen until i finaly decide to the abyss of the out of bounds ! :)

Put in a game it would be very nice and cool and an awesome genre ! Nice job here !
