Thank you for the game!
I really adored the music and the art style! They both sucseeded in creating levels emotionally ditinct. I always struggle with finding time to elaborate on musical design of my games, so when other people do this right it always amazes me and prompts immediate respect. The art style is very effective at making scene 'breath', while keeping details to the minimum to not distract you from the action.
Platformer felt good for the most part, although I would say that level design does not work on conveying emotions as well as music and visuals. I had hard time understanding what level corresponds to what stage of grief judjing by the level design alone. The difficulty progression felt very generic for any platformer, wich is a loss in my eyes. I liked, though, that while every stage before the last one ends with falling into the pit, the last stage is fully dedicated to overcoming pits. This felt very cathartic.
The ending felt very abrupt and somewhat spoiled the experience for me. The change was so sudden and sharp, that it made me smile a bit, despite the subject matter. I think making transition to the last scene more smooth would have added it much needed emotional weight.
