Loved it!
The mechanics were easy to pick up. Artstyle was fitting with it's messy strokes. Enjoyed the music a lot too.
Only thing: I got stuck for maybe 15 minutes on the last level. I thought I'm supposed to pick the flowers up in a specific order and didn't notice the door is open! Maybe alternating the "This isn't right..." line with something like "Maybe they're not meant to be picked up at all" or something even more direct would be helpful. But otherwise I had no problems going through the levels and had fun!
And lastly, the story hit hard! Didn't expect it, short, deep, creepy, I got chills at the end.
Nice one :)
