Nice idea! I like the bound theme ^^
In my opinion conlission of Guide is too OP, you can bodyblock many things to prevent damage(even boss) and sometimes it's a pain in the ass, like when you need to run around the trees and so to pick up a coin or smth. If the pain is intentional, perhaps the boss should be flying?
If i were you I would tune balance a bit like Guide and mobs speed++, Guide damage++, skythe length---. So your character needs to run arond Buddy(or through). But maybe you chased other feelings from player.
Nice game overall!
