Thank you!
The buttons are hooked up the wrong way around. Didn't catch it during the jam though...
It was a bit confusing in the beginning, a few more explanations and examples would have been great. But the idea is definitely great!
My biggest problem, however, was that the game window was way too big for an in-browser game. Scrolling down to read the explanation, for example, was barely possible while playing.
Since it's a jam game, I won't talk about minor things or polish and focus on the main impressions it made on me instead. Without any particular order...
