Really impressive polish, the UI, spritework, and effects felt very cohesive. I also think the level design did a good job of showcasing the core mechanic. I didn't love the character movement speed at first but after playing a bit I think it fits the game well and it feels more like a puzzle game than a platformer so I think it works. The main frustration I had was just that trying to position the logs could be really fiddly sometimes and it felt a bit difficult to snap them in the way I wanted but as you mentioned you had to mangle godots physics engine to get it working so the fiddliness is unintended.
