I'll admit I wasn't expecting a lot from the splash image, but this really surprised and delighted!
I liked the nice smooth controls and found the combat surprisingly engaging. The first time you see those big enemies! I liked revealing each individual cave and having to deal with whatever was in their up close. I do think the combat starts to dissolve into spamming, but... that's kind of Zelda too? Overall, solid work across the board.
Apologies if this is an insulting question, but did you compose the music? If so, excellent work! It really adds a lot. If not, please credit your sources.
