I will add a small tutorial. You have to use swiping (up to jump, down to crouch, left/right to start fight in zone, then swipe emblems in shown directions). You can't play the game on PC unfortunately.
I'm going to upload a new version with a lot of improvements and content. Actually, I've submitted this game for itch.io mostly for testing purposes only on smartphones, and implementing mouse controls will take a bit of time. However, I will try adding mouse controls for the next update.
