Your game reminds me of Zelda Link to the past and stardew Valley had a baby. I enjoyed playing it.
Love the colors and feeling of the environment. It was a nice feeling to explore a random cave and find something rewarding.
The character design are well designed. I like the main dude, he reminds me of shaggy from scooby doo, itd be cool to find a companion that looked like scooby and he'd just follow you around on your adventures.
The one thing I do have to say is the swing of the sword feels like it has such a small hit box, it's like the left corner of the player character is his weak spot where his sword can't reach. If he had increased range and attack speed or some way to increase his speed and attack range, that would be cool.
For the fungus enemy it'd be cool if we can hit that purple projectile back at the fungus.
Cool game tho, I can't wait to play more in the future!
