I actually really enjoyed your game! Something about stacking blocks triggered those infant parts of my brain that just wanted to make it perfect. I love the concept and definitely think you can make a full and fun game from it. Even this however kept me entertained even to the end! I’d love to see even more shapes added to it as well. Maybe change the sfx up a bit (they were a bit obnoxious) and add some background music (plenty of free assets on sites like Pixabay) and you can have a really solid game on your hands! Great job :)
