You’re strange. Earlier you asked for cheats, and now you’re asking for a gallery. Your statements are inconsistent, lol.
Animation gallery will be added in version 0.4, after HTA & LSHT are updated to version 1.0. So be Patient
Cheats = to unlock the gallery faster.
As simple as that for those just wanting casual gameplay with an H-game. If it is written and put on top of the main posts the creator writes, such as "When 1.0 is finished and released, then a gallery for people who want to just see the scenes." Something along those lines.
The names change, some characters are different. I respect that a lot of story and hard work is going into this game. But as many people have said before, a lot of this is confusing with the story, and it takes a lot to just get an H-scene.
I don't think this game needs cheats, it's quite easy and you have a lot of tools to make the ghost hunting easier. The game deserves the time to play it and go through it, if you don't have time im sure someone will post a full gallery save or full save when it's done. Just be patient.
Either way the game is not that difficult and you have extensive walkthroughs to help you get through everything plus the discord server where you can ask and check any doubts. It's worth playing it.
