I'd really like to see this game a with a few more assets. Exploring felt nice, I can't complain about the platforming and the grapple mechanic was really fun to use. Combat against the little mobs in the world felt a little slow and tedious, I didn't feel threatened and I didn't think they were dying fast enough. They were just getting in my way as I tried to explore. I'm not saying it should be removed, I'd just like to hit harder.
Good game, keep it up.
