Tentikun 2: That time I got reincarnated as a dungeon

You are Tentikun, a tentacled little creature that got isekai'd and reincarnated as a dungeon core in a fantasy world. Your job is to design rooms, spawns monsters, set traps, and manage resources to defend against invading adventurers. Choose to make the lives of these adventurers as difficult, or rewarding, as strategically appropriate. As a dungeon core your goal is to lure adventurers to explore your dungeon so that you can absorb their Æther. You also have the option to defeat the adventurers to absorb and turn them into Matter. Æther and Matter is needed to power and expand your dungeon but you need to keep a balance between defeating the adventurers and letting them escape, assuming your are strong enough to have this choice. Being too aggressive will result in only low quality adventurers daring to explore or the guild sending an elite party to clear out the dungeon.
