Really enjoyed this game you made here. I spoilerd myself a bit by reading your answer to ilPrinnis comment. This though led me to have a goal for playing it. Open the door. You obviously tell this the player too, but I believe it is easy to think that reaching full hearts it the goal here and therefore overlooking the real goal, to get healthy and back into the world again (atleast that was my goal).
I enjoyed solving the puzzle of how to wake up each morning and end the day that my character can wake up better next morning. Big steps were for example finding out that I shouldn't cut myself. I did this often because I wanted to end the day with the most happiness, but by doing this I hurt myself in the long term.
I really enjoyed finally seeing my plant starting to live and growing each day :D
The music feels perfectly integrated into the game and is a good fit for it.
Great journey, nice art and just all in all a great game.
