Very fun game. As a dungeon crawler fan I loved the gameplay. I detest backpack/inventory management, it was always my least favorite thing in Diablo I & II. But the ability to reorient things made the management into a puzzle minigame of its own and that was good.
Graphics are fantastic, I absolutely love the art. Extremely well done with a very unique style.
Soundtrack is good, music sets a nice mood and the sound fits.
Gameboy Soul is here, I could see a game playing like this on an old GB.
Quirkiness is here, the game is certainly unique!
Secondary theme interpretation: There's gold, it is old. Check and check!
