Is this a bug?
I assume so? When you walk into that room, a scene should trigger where you have to fight them. Are you playing on the current version (3.1.1) and was your save data created in that version.
I resolved It redownloading the apk and now everything is going smoothly.
Compliment for that awesome game! And i wanted ti ask you if you have a discord channel or a channel where you Say Things about the game
Mainly just a patreon for now. I may open up a discord in the future.
