hex tile world sort of reminds me of those 'Civilization' games, although I didn't get very far (ran out of energy, odd since I'm a 'celestial being'; I should be able to fly/teleport/smite all villages with fire)
> smite all villages with fire

You're supposed to help them XD
It is indeed heavily inspired by the exploration mechanics in 4X games like Civ, Humankind, Old World and such.
Running out of energy is intended: the game cannot be beaten in one incarnation, since every world needs a skill only present in another one to be completed ^^
The Game Jam's theme is Loop after all, dying again and again à la Edge of Tomorrow, then retrying but this time with the knowledge of the previous lives was one of the core inspirations!
But unfortunately, since I couldn't balance the resources management in time for the Jam, the game might be difficult to beat without tryharding, I know that :/
As for the in-game explanation: you didn't ran out of endurance, the body you're possessing does :P
Unique Curiosities!
- Towns, Treasures, Camps ans Ruins are common Curiosities, there to either let you Rest for exploration or earn currencies (Food, Gold, Influence or Relics respectively)
- These currencies can then be spent in unique Curiosities to unlock skills, which help you explore further in order to find the ending events
- Skills are retained between incarnations
- They are only active in their respective world, unless you unlock the Ethereal skill [Shared Knowledge] branch on the hub screen
