Very solid falling block puzzle, I found the controls worked really well and the aspect of physics to one piece falling, etc was a good addition. The silliness switch is great too. The one thing I would suggest is having a way to quit to the menu while playing rather than only quitting the full game. Would make it easier to try normal and then try the silly mode without having to reload the page. That's a very minor thing though and would be less noticeable outside of a jam where you want to see all the features for rating.
