This is polished to the max, amazing! Everything just feels so complete, the music, the animations, the puzzles, the mechanics. The only little nitpick i had was the scoring system which is a little unintuitive (at least to me). I though ending with as much oil left in the tank as possible would be better but i think after playing trying to maximize the dug up tiles is better. That's a really minor thing though everything else about this game is amazing. Including the theme interpretation which we interpreted the same way and i think its fun to see how different the outcome was in the end. Amazing game!
