This was a mixed bag for me and I mostly appreciate what I believe to be the game that you intended to make rather than what is here right now.
I finished the game but I was happy for it to be over. I liked it, but I'm unsure if I enjoyed myself and I'm also unsure if that's a good thing or a bad thing. This definitely felt like a case for "games as art" as I felt the mechanics very stressful(and not in a fun way) but quite evocative of the intensity of confronting oneself and performing deep inner work. The very long initial sequence with the bodies is the best example of this, definitely had a sigh of relief once that was over. The same goes for the reuse of level graphics, the simplicity and repetitiveness of the gameplay, the sluggish movement of the character. All of these things got on my nerves but in the context of the story make sense. The story/writing was lovely and was definitely the main hook that kept me playing so well done there but it was filled with little spelling/grammar errors that took me out of the experience and there wasn't really enough of it before going back to the repetitive gameplay. The art and music were really great though and I appreciated the mixup of symbolism for the obstacles/environments.
Overall I think this was a good effort and I gotta commend you for doing something a little different. A little more time in the oven to fix stuff and polish the gameplay and this would have probably been a favorite.
