I liked the game, both the art style and the music worked quite well together but initially it was very difficult to understand what the objective of the game is and what the controls are and what I should be doing. I believe the game is like a game of tag ? If so I think a way of seeing who is currently tagged would be helpful as well as a preview of the controls would be beneficial.
Having multiple different levels also helps keep the battles different but again without knowing the controls and having to trial and error to find them, I got stuck in a pit until the timer ran out and the next level began.
Overall I enjoyed it but something I would say would go a long way would be to have some sort of way to tell the players the controls.
