Very intriguing concept and immediately compelled me to play more. Also, I was sitting at the bar when I started playing and someone noticed it over my shoulder and asked what it was and if it was on iOS. I told them it was open source so probably not but they noted the name anyway. I think you've got something good in the works here!

My only notes so far are that the options are a little confusing at first glance and that the area where you drag shapes from is too close to the zone where you drag up to switch apps so I kept accidentally switching while trying to move pieces.

Otherwise great work! Looking forward to losing track of time playing this in the morning before work 😅
