I got as far as figuring out that you can switch between the 2 characters, and that there is a way for the boy to punch the entities flying through the portals and gain points. I think probably just needs more indication of the objective (or if it's supposed to be discovered through trial and error, some kind of hints about what to interact with and what the possible inputs are)?
I could not get the score to go up? I could also run all over the map, going outside of the arena bounds and through the portal.
Very nicely done on the visuals, I just wish it was more playable!
