It's a Zelda clone, where the overworld and dungeons are all randomly generated. The randomness makes the landscapes look messy. From a mechanics perspective, I don't feel like it actually adds anything either, except perhaps making the game different if you wanted to play it twice. I wasn't a fan of the glitch stuff - particularly at the end of the game when it's relied on as a mechanic where you can teleport and glitch through walls. The bosses are pretty interesting, but anything else is super easy to kill. Definitely play it on a controller; the keyboard controls are basically unusable.
It has either 8-bit or 16-bit style graphics which you can switch between, although this feels more like a gimmick you might use once then forget about. I tried the 8-bit version, but it was difficult to tell what was scenery and what was an enemy.
