Let me hop onto this love post too! I really appreciate the mining-game, the battle screen, the stat growths, the slider minigame. Never have I been so engaged with the gameplay mechanics of a free game of this nature! Something that's both fun, and hot. Not to mention all the characters, animations, and comboing of the palettes+positions+sizes+accessories. This is easily one of my favorite games even in it's current state, and I've played a lot of indepth gameplay focused games. Anything that gives this level of freedom in a comforting rpg-like progression is amazing, and deserves it's place as a holy grail title of 18+ games!
I have the clearest sense that this dev puts so much love into this game, and I respect that adamantly.
