I love the atmosphere of this, it really pulled me in. I played three times to see all endings; red-green-red the first time, then all red and then all green. Not entirely sure I'm cut out for the job of taking over in the spirit realm...!
It's short and sweet. Melancholic but hopeful. Pretty impressive to get those feelings into a few scenes! Also the transitions between the close up portions and then the dodging areas was nicely done.
On my third playthrough I held right as soon as I started and this caused a glitch where the player couldn't be seen, only the 'aura' of light around them. Luckily this was enough to get to the first memory and after that the player was visible again. Speaking of the aura, I really like how it looked when the angry spirits get close and their glow shines onto the player's, it's a neat effect... and also my excuse for the many times I got hit by one. I'm glad I didn't have to restart from the beginning each time that happened, however starting from the last memory feels much more punishing when it's two screens behind, (when trying to get to a new memory) rather than the middle of the current screen (when trying to exit from a memory.)
