Wow. It reminds me the memories playing outer wilds from the very beginning. Nice work !! The stylized 3D graphics really makes it impressive and the idea of inverting the world is stunning, with the beautiful graphics and design.
One thing is that I found it very discouraging when fall down from some platform and had to start over, maybe quick reset to last standing point / fall damage + restart or some level design can help. Also the physics feels a bit strange, but it is a jam submission so xD
Love the design of this world, romantic xD
