This is a pretty impressive entry! The art style is extremely good and goofy, the music is excellent, the gameplay is super fun, and the items are just hilarious. Why there is a hydrogen bomb for you to balance is beyond me. Also, no more swordfish, please. The controls are simple to learn, but the game is fairly difficult, especially if you want to stack too much on it. I'd say it fits super nicely! And the best of all, the game is super polished too. Well done!
For some small criticism, I'd say the object takes a while to be solidified into the stack, and it makes a lot of items just fall off. It should be more fun with more items stacked on your balancing board, but I digress. I also feel like the game is a bit unclear on how much "unstableness" will be tolerated until you fall. Other than that, the game is very well made! You should be proud of yourself!
