I got the broken seal and reached the top of the mountain, couldn't find anything important after that so I assume that's the end. This is super impressive for a solo project, something like this requires an extremely wide skill set. The art and music are of very high quality, especially when taking that into consideration. Also the first game I've seen in the jam to implement control rebinding so that's a huge plus too.
There are some things I would criticize though. There is seemingly no incentive to fight most enemies as they don't really get in the way, don't drop anything and some of them, especially early game, are actually pretty dangerous.
The game overall feels very eratic with how fast everything moves and how abrupt changes in momentum are so even easier platforming sections could take a couple of tries because of the controls.Maybe as a result of that the melee attack feels a little unreliable.
I encountered 2 bugs, the first had the wanderer protector spawn behind the barrier and going left in the blue cave room after flicking the lever softlocked me multiple times because the camera would move to that spiky platforming area between the grassy area and the mountain. However, it is really cool that you implemented a save system, made those slip ups way less impactful.
Great job overall!
