Now where have I seen those sprites before?
In all seriousness, it was great fun! Took me a while to progress at first because of how small the item pickups were.

Absolutely! Sprites are from Mystic Quest, aka Final Fantasy Adventure, aka Seiken Densetsu, as mentionned in credits on itch game page and in game!
That is my favorite game boy game! I encourage you to play it. (I personally enjoyed it more than zelda links awakening)
