High level: hitting the retro game tune and style, nicely done!
Rather buggy, not sure how I entered a battle and then found myself at half health, it started asking me to attack? But I couldn’t press anything. I came across the settings screen to change music/sfx audio levels - I highly appreciate that menu existing! Good accessibility. Might recommend showing up front or at least tipping off there’s a menu via some icon, as I only found it after wiping my hand across the keyboard to see if I could make anything happen during the battle :D
