I... really don't know how to feel about this game. The visuals are unique and interesting, for about a minute until your eyes start hurting from the craziness of it all. The menu options are ridiculously high detail for a game jam game (I mean saving/loading and adjusting resolution and bloom, REALLY?!), but the saving is unnecessary for the kind of game it is and didn't even work when I tried it. The movement feels good and even has human feet and shadows, AND you can interact with stuff. However, if you press E to read a piece of paper it very clearly states that it is part of the Horror FPS Kit by Thunder Wire... which costs $45. This kit is the core of the game, as it provides the UI, character controller, inventory system, etc. While Mark's rules do seem to allow paid assets (as long as you have the legal right to use them) it doesn't allow for pre-built code: "The vast majority of code must be written during the jam". Asset kit aside though, there's not really a clear path for the player to walk, or a goal they are trying to accomplish. I walked around aimlessly for awhile to see if there was something more and just ended up finding the edge of the landscape, which wasn't sculpted down to finish the islands. I really want to like this game, but as someone who has built my own landscapes and character controllers in Unity, I can see just how generic this game is behind the filter. Apologies for potentially overly-harsh feedback.
TLDR: I like the aesthetics, but there's a lot of flaws here including the fact that it likely doesn't fall within Mark's rule-set for the jam.
