Love love love the artwork on the title screen!!!
Very cool concept with the heart beating mechanic. Unfortunately, I couldn't find any enemies or new places for me to go, so I wasn't sure what to do other than walking around and pumping my heart. Although, I did see some inaccessible areas, so it seems maybe there was more to the game that I wasn't able to experience
I would suggest some more on-screen pointers early on, unless this was just an unfortunate bug!
Very solid concept and I would look forward to you exploring this further
