The hectic nature of the gameplay pairs well with the wide variety of objects that you can stack together! It feels almost like Katamari Damacy with how many random things you can interact with, and playing with the shapes of each object makes it fun to experiment. The attention to detail in the sprite work is also very charming!
The only thing I find myself wishing for are stackable objects with different properties to them, like some that are slippery or some that are breakable. I think this would add some variety to the gameplay, as well as encourage the player to think a little more carefully about what they should stack.
Overall, this ended up being a very addicting little game. Easily replayable and well thought out!
