An awesome physics base puzzle platformer. There was a really good balance between planning and execution on most of the levels. My favorite part of this game is the fun amount of experimentation allowed. I had a few aha moments that are great in puzzle games. The first was on the level with one bone and two boxes were I used the bone as a catapult by throwing a box down on one end; the second was applicable to all levels where I stood on top of a box, jumped, then threw and released quickly. I imagine both of these were intended, but they felt "discovered" in a way that was very satisfying but intuitive. Very well done on creating that experience, it's hard to achieve. I wish there was a bit of leeway with death on held objects, mostly when you're under a box and you lift to drag it up. It doesn't feel like it should kill you, but I imagine implementation of that could lead to some difficult work for other interactions. The double spike level was indeed quite difficult, but I'm glad I persevered through it. Great stuff, you've achieved a lot here.
