First off, the presentation is fantastic - the UI and art assets are super polished and the music fits the vibe well.
As to the gameplay. I think the core works well - the systems for gathering resources and building structures are super polished, but I didn't feel much of a sense of progression while playing the game. It took me a little while to realize what the 'summoning' theme had to do with things, and I think the idea of summoning resources with which to harvest is a fine idea, but I was left puzzled as to how the 'faith' meter grows - does it just grow automatically, or does it increase with certain factors?
Also, I thought that the jokes about the jam deadline were funny - I hope that you're able to finish those features in the future. Good work, and I look forward to seeing what you make next.
