Aesthetics very much feel like GB/GBC Legend of Zelda. Gameplay feels in the vein of Angband. Very polished for 10 days of effort.
Minor nitpick: I was under the impression the GameBoy lacked a triangle wave channel for its sound system. Musically this sounded more NES than GameBoy to me as a result. Sounded great regardless, though. (Edit nevermind I'm pretty sure that's the pulse instrument and I misidentified it)
