I've been following this game for a while and feel possessed to write gameplay fanfiction for it.
Game begins with Hero Boy (the player) seeking shelter as an unearthly fog or mist descends on the dark forest path Hero is walking, skewering all telltale signs that he is walking deeper into dangerous territory (this is all told through cutscenes) This is where everything seen in the UTW demo comes in, albeit maybe made slightly easier in difficulty as this is the player's first introduction into what the game has to offer. After the Witch is defeated she *poofs* off somewhere and Hero finds (through cutscene) shelter at a nearby cave or a very foreboding looking house owned by the coven of witches the Witch you just defeated was a part of. (maybe after her defeat she gives you directions to the place in the hopes of further trickery?)
after this, the very limited "open world" gameplay shows up. The player has about 300ft of roaming and exploration distance to walk, run, and maybe jump inside a very linearly designed area (combat of any sort only happens in story battles as seen in the Under The Witch demo), everywhere the game's story takes the player will be like this in terms of roaming and exploring. Take for example when you're at the Witch coven cave / house. You may walk around the cave / house, but anything that looks like an exit to the outside/back to the forest will be an invisible wall to the player unless going outside is where the player is supposed to go in order to progress the story. If the player goes off the beaten track within his limited space he might be able to find a H-card of sorts to unlock hidden sex scenes, or maybe you can find the room of the Witch you previously defeated and as an easter egg you can observe that her rooms decor and furnishings are all made out of the bodies of all the fallen heroes she has broken (a reference to the failure state in the Under The Witch demo where if you lose to her she makes you into her eternal chair to sit on)
Maybe you can talk to NPC characters who give you simplistic side quests all leading back to the main story that is all told through pre-fight cutscenes and very linear setpiece moments.
Maybe I've been shitting and moaning far too much but I think something like this sounds far more reasonable than an open world for a very small group of developers. Sorry if my post cluttered up the thread, I really just want to see this game succeed.
