This is a REALLY high-quality game! The fact that there's no audio or physical feedback when you attack enemies is literally the only thing that stops it from feeling like a genuine GBC release to me. If you're reading this and on the fence about buying it, don't be! If you like Metroid games and GBC vibes, this is a must-have, easily a top 5 in this entire homebrewing scene from my perspective, especially now that the price is more reasonable.
