The graphics and music are stunning, truly a beautiful game! I have a lot of trouble with the controls, nothing that hasn't already being said in the comments, and I must be missing something, but I'm stuck here in T pose near the beginning :
This happens when I use the E key to move the heart and immediately hold W and D to move right up to the next platform. (If I don't hold the keys immediately, the heart disables itself and I have no choice but to kill the protagonist to restart.) When the heart I'm controlling touches the heart on the platform, this happens.
If there's something I can do differently to progress further I will, because your game is amazing.
