Works like a dream on native hardware (using Everdrive N8)! Loving it so far and will definitely be interested in the full release.

Played this with bats, had a blast on it! Unsure if maybe I should have done this a little differently, but I did find the first dungeon very challenging (I gave up after about ten deaths haha), as a lover of classic Zelda I don't think challenge is itself a problem, but the difficulty curb might be a little high?
All the same, the game and its soundtrack are gorgeous, I was seriously impressed and look forward to playing it more!
