Review in progress
I will update this as I get further in. A fourth element, Wind, would not be a bad thing to complete the elemental necessities; you can have it be strong against Water but weak against Fire (because wind spreads fire). The costs of upgrading at MagiMart seem a tad high for the early game. Taking those costs down a tad would still lead to satisfying progress. Nothing has changed, except I had to play the game over again.
