Really great game, I love the objects falling part. Here's some suggestions:
1. Make it so that everything falls at the same time,
2. On tutorial level , when chair falls, you should remove the option to go down,
3. The whole arrows should be clickable(not just the tip of it) or things could be moved with arrow keys/WASD also
4. I noticed a pause icon, but I would be great if you can also do that on esc
