I don't know if you're still working on this game but it's cool to see another zelda-like game! Couple suggestions:
- Attacks and movement should be 4 way
- Sword attack is much too small range to hit things, consider making a slashing animation and using an invisible animation
- Bones and Projectiles should react to walls or other colliders
- Spawn should be a safe space so you can read the tutorial without getting attacks
- Your art should all match with 16 bit, 8 bit, or 32 bit amount
- Music loops way too quickly and becomes a nuisance fast
Impressed with what you have so far! Looking forward to more
