Cape's Escape Game 4th Room (2021)

The main character invites his girlfriend Todomi out on a super low-cost trip to the hot springs. Of course, Todomi rejects him.
Being super low-cost, he can’t cancel his trip. Heartbroken with tears in his eyes, he forces himself to set off on his trip.
 But even 1980 yen is way too cheap for a trip with meals included.

 Sure enough, turns out that the main character's one night stay is not at some ordinary Japanese-style inn. It comes with an escape game.
 Solve riddles to help the main character escape from this traditional Japanese hot spring inn.
