Tasokare Hotel

Adapted from SEEC's game, 'Tasokare Hotel' (Twilight Hotel). Tasokare Hotel is a place for souls who are neither alive nor dead. Lost souls can stay here to recover their memories and find the path they should take. The protagonist is Nekko Tsukahara, who arrives here due to an accident and decides to stay. Since she hasn't recovered her memories and is very bored, she decides to become an employee, creating a touching story with the souls who also came here. Travelers' rooms are formed by their own memories, and you need to investigate the rooms to recover them. There are elements of mystery and a debate segment in the game. Here's a link to the game (you can earn gems on playio). It doesn't matter if you play the game first or watch the anime first. However, for the game, it's recommended not to buy the Steam version first, as it differs significantly from the mobile versions. The Steam version lacks some fun mini-games and gacha features and is paid. It's recommended to play other versions first and then purchase on Steam if you decide to support it. Additionally, the sequel 'Tasokare Hotel: Ichirei Ichirei' is available on Google Play, but it seems unavailable for download in Taiwan. If you want to play it, you'll need to use other methods (like turning on a VPN or downloading it when you visit Japan) as direct download isn't possible in Taiwan.
