Y'all put out a consistently high level of quality I've noticed, your games feel very thoughtful and well polished. They feel like they belong on the front page of newgrounds or addictinggames in the early 10's.
This game is really enjoyable to play, everything is very "slow panic" and it's super clear to figure out exactly what's happening and how to play intuitively-- you've done a great job designing the learning curve. The actual puzzles are simple, but satisfying, the the game is juicy as hell with all the objects feeling alternately like a light block of wood, or a delicate ball of caviar.
The indirect control is a very creative use of limitation.
Overall, this is great, one of my favorites :)
