I enjoy the game quite a bit, running around shooting and collecting meat.
I think if there could be some improvements, there could be a sound or particle effect when you collect meat.
Also, I think that because the anger meter is pretty short, it discourages me from wanting to run around on the other side of the arena. Maybe there was a treasure over there I missed though.
I reached the 2nd level, but the anger meter was too much for me to maintain.
Also gotta love the cucumber image on the wall, haha
