I think I'm impressed on the graphics, but yeah I feel like its been hit with the overscope for the main mechanics.
Thinking what could be done:
I wasn't able to make a comment immediately (even slept) as I needed to think what could I say here, as the main thing I was grasping on was "if I were in the developers' shoes, what was the minimum amount of game to add enough replayability." Because I really see the effort. To do the tectonic mechanic, you need the world map, a way to select each plate, a UI to navigate in the side and being able to touch the world map, being able to set the direction of the plates, and displaying which regions are affected to generate score... It's a lot, and I do empathize why the tech tree was delayed.
Because there is a major inspiration towards Plague Inc., which in there the depth is being able to spread (grow) w/o dealing with events/cure and the tech tree is the main way to navigate towards it, it's interesting on how the game instead focuses on faults, and from there the main engine. The one thing I thought is (suggestion), can this aspect be given more depth, maybe goals to concentrate faults via a multiplier to score at certain faults to be able to navigate and push the tectonic plates in that direction, or anything that uses as much of the existing mechanic you've made so you don't have to do more work. Still I'm uncertain if it would be faster than implementing the heal and tech trees, so I'm not committed to this idea.
I'm just yapping really, it's really difficult for me to think and I still appreciate the game on what it is.
One bug I found:
I think there was a mismatch with the direction I set and the displayed direction on the side...
Still repeating at that paragraph, I mean its a lot of effort in the game music, art, and implementation of mechanics, it just fell off with the replayability aspect, and thats kinda what makes game jams hard that not everything might be added, so which is priority. And even still, the main core of the gameplay loop here is big number go up technically lol, so it does work on that front.
Still, it's nice, and thank you for submitting to the game jam!
Edit: added some stuff
