Wow this is ace! It's so interesting that the random jump cursor turns the game into a fast-reaction game to press at exactly the right time. It certainly had me concentrating!
Love the art style and atmosphere. Keeping a limited colour palette certainly helped.
My one criticism would be that the cursor would often go off the screen, especially if I was near the edges. Was a bit confusing. Should be an easy fix to restrict to screen area though.
I enjoyed that! Keep up the great work!
