This is a big game to try and make in only four days, and ya'll did a great job! I love the Zelda and Outer Wilds inspiration. When the theme was announced my first thought was Outer Wilds and I steered away from it because I felt the concept was too big for such a short jam, but I'll happily try the games that went for it! This game has a lot of charm, I really like how it looks and sounds!
Two pieces of feedback: I think the hitbox on the sword needs to be bigger. Almost all of my deaths were me trying to fight enemies and just barely missing. It's also hard to the elevation and danger zones in the environment apart from walkable space. I read below that it's more obvious in a post jam patch which is great! This one area on the way to the sword however I think is either supposed to be a death trigger that's bugged, or looks too much like the areas where you will fall. It's got the tree stumps for the grappling hook and a heart peace on the other side which makes me think you're supposed to die there... but the area afterwards you can walk over identical looking spaces too.
Awesome job, ya'll are crazy ambitious and I can't wait to see more!
