Very cool Game!
Watching the wood burn and the sand fall feels really satisfying. The puzzles are nice, getting more difficult over time. I found it a bit weird that the character was off-screen while you created the wood.
I feel like it doesn't fit the Focus Multi-Use perfectly since you have different ways of interacting with the wood depending on if you have to create or destroy it. But other than that, really nice, polished game, well done.
