Stunning
Before diving into my review, I just want to take one sentence to say outright: this is awesome.
Story-wise, I loved every moment of it. Even the tutorial-esque intro level provided a great bit of insight to the story. It was enjoyable to explore the world while seeing how huge it really was. Learning about the surroundings (and the secret items) that allow the player to think about "what happened here?". I'm not sure how I felt about where it ended, well, without spoiling anything, I assume it was supposed to be open-ended.
The art, and especially the music, was great. The style really fit the mood and feel of your game. Not much to criticize here, so
moving on to gameplay. Skinny is longer, and as others have said, more challenging than Coma. I liked the length of it, and the saves were in convienient locations. It seemed like the right amont of challenge (for the most part) and as I already stated, I enjoyed getting to explore and wanted to continue playing. I did encounter the falling-through-things glitch, and the color-gates were aggravating on my playthrough. Alas, I refresh teh page and see you already fixed these now, lol. Good job.
Overall, this is a fantastic game, all around. Would definitely recommend.
