Great jam game.
Music, design, SFXs are great.
UI is mostly great, aside from building description covering leftmost building slot.
Gameplay is nice at start, but gets very limited by cooldown of sacrificing. Works fine for jam.
Objective part is over, rest is subjective:
Upgrade system can use some work. Upgraded level should always give more stats, than previous one. If it doesnt - combine cost with next one ’till it does and call it one level.
Faith, research and food should scale with amount of people. Seems wrong that vilage have no followers, but faith increases at rapid speed. Same for food supply increasing without any people to collect it. Same for research.
But, it’s all small-ish details. Great job.
