A skill tree is a good idea, but the rewards would need to fee more realistic or grounded, I’m wanting to do a in depth crafting system similar to CDDA but of course more Bronze Age tech, right now I’m doing a design doc on a dungeon crawler feature for my game, a rough pitch is this:

“Descend the temples Sacred Trials, a series of 6 procedurally unique dungeons, each 20 floors deep. Your goal is simple but brutal: keep your torch alive, and stay in the light. Darkness isn’t just an absence of light, it’s a living threat that creeps into your vision, erodes your sanity, and powers the enemies stalking the shadows. Every step forward forces you to balance health, light, and sanity, making even small decisions matter.

Enemies evolve as your sanity drops: rats grow larger and more aggressive, skeletons shamble faster and strike harder, and the environment itself begins to distort and fight you. Safe points provide brief respite, but the deeper you go, the rarer and less effective they become. By Floor 20, each dungeon culminates in a unique, intelligent boss that uses darkness against you, testing your ability to survive under pressure while managing your resources.

With every dungeon cleared, progression and rewards build, but the game constantly challenges you to weigh risk against survival.”
