Digging for treasure really hits the “Old Gold” theme, and the black-and-white graphics bring me back to the original Game Boy. I also really like the scale of the character to the world. It’s interesting visually and feels like it would be easy on the eyes on an original DMG.
Please update the browser settings! I had to change things around to see the full game. Either enabling fullscreen or setting the game resolution to 480 × 432 would make it much easier to play in the browser.
Feels at home on a Game Boy.
