I really enjoyed this one, and not just because I have a soft spot for visual novels and Ren'Py. The NPCs are unique and cute with hidden depths, their designs very nicely realized by the original art. I don't know if you made the equations easier after the Jam, but I didn't have any trouble with the minigame when I came back for subsequent plays (now I think the issue might more be that the instructions are written in a counter-intuitive order and are difficult to understand without seeing the interface). I wish there was a touch more complexity to the outcomes but the limited branching makes a lot of sense for a Jam game. I could still easily see myself coming back to this, even years from now, to play through all the endings again! Excellent work!
