Thank you for such a detailed and well-thought-out review! We're so glad you enjoyed so many aspects of the game experience. We completely agree that a tutorial stage and a more relaxed object-placing rule would make the game easier to understand. With the time constraint, it would just be really difficult to add a tutorial stage. Additionally, the strict object placement is necessary to prevent physics glitches and bugs. You may know that Scratch doesn't have a built-in physics system, so we had to hand-create the gravity, object placement, and breaking all ourselves.
We appreciate you taking the time to play and review our game, it means a lot to us!
