Very original & cool combination of idle game and drawing!
I love that it is possible to play the game very laid back, and have drawings that take a long time to complete or you can try to optimize it as well as possible to gain resources much quicker.

The only thing I don't like too much is the total RNG of artifacts.
Sometimes you only gain +resources/+drawing artifacts when you need the other, but that is only a minor complaint.

I also really like the setting and the types of drawings/glyphs you have to make. It would be cool to build up on that system to combine glyphs or go even deeper into the magic and/or occult theme!
