This was a super interesting game, with an absolutely lovely art design! I really like how distinct and flavorful the different areas of hell were (ice, lava, eyes, bones, etc). The puzzle design was very interesting, I love the concept of making gated progression by putting together clues in the environment, rather than simply based on new abilities.
I do agree with a lot of the comments that some of the puzzles were too difficult. I think one of the main pieces of feedback I have for this is to give a clearer symbology of what clues go to what puzzles, and where the starting points for the various solutions were. I felt like I uncovered most of the pathway clues, but was often lost on where to start the path, or what order to do the paths in. Anyway, this is fantastic work, and I'd love to see what you come up with next!
