Finally completed the game! This took me a while. This is such an interesting cookie clicker clone with a twist. I do like how the cultist system works. It's quite unique that you can actually sacrifice productivity to gain other resources. The different sprites of the biscuits are also very cute and it add to the charm of the game. The balancing of how much stuff costs and how powerful they are felt a bit off, but for a game like this, it's next to impossible to do it right with the amount of time the jam has, so I'll not complain too much. Generally, this is quite a nice entry!
For some criticisms, I'd say the controls were not very good. Using WASD solely for traversing across scenes felt unintuitive, as least if there's some transition animation that moves the camera to the correct screen would help. I would also suggest adding arrow buttons to the screen to allow mouse-only plays. I would also suggest making the tabs actually work like tabs rather than separated drawers, which will certainly help with the thousands of misclicks during my playthrough. Last but not least, since the size of the biscuit is also a resource, that should always be visible to the player yet currently it is pushed outside the screen.
Anyway, this is still a nice game, and quite a good time sink as well. Well done!
