Once you get to the sky stuff, more specifically earth and wind, the game progression just drags on forreeevvveerrr. There's no clear method for how to win the fights other than to just wait and hope you can incrementally upgrade enough to finally beat them and it gets a little frustrating. Could definitely use a rebalance, if that's not the intended gameplay. However, this is a lot of fun before that point. Everything on the mountain and even the fire stuff is really well balanced and a good mixture of active/passive.
