I love this idea and it's really fun!
One note, for some reason the web version (using chrome) was broken for me: basically, when I pressed space, the game would immediately end with a bunch of stuff stacked out of nowhere, and clicking left to right would snap to the left or right and not go to the middle.
I downloaded the windows version though and it worked perfectly fine! I rated based on the windows one, not the web version. Great work!
