In every aspect it is pretty solid i hate the speed-flying thing that teleports to me but it can be some small bug with the clock working differently on the website with my PC config.
Art is amazing but it is kinda boring. With good skills, you can kinda not move from one place. I think you need to think more about upgrade design because if it doesn't have any downgrade the challenge disappears in seconds after 1 minute mark I was just standing still. Oh, and the beginning movement speed makes you don't want to move even more because it is so slow.
I believe better to make tutorials or something to teach players in the game and it is easy to loop audio in the game making it impossible to play(bug if you start randomly pressing E after you start the game).
