On the first section of the game, I thought to myself: "Oh hey, cool, this could be the next WarioWare or A little to the left-inspired slice of life game! I wonder, why did the description say it's so short? Oh.. That's why..."
Yeah, the second section of the game has a completely different tone. The simplicity and contrast between the first and second sections really enhance both the story and gameplay. And yes, the game should definitely keep its original style and length - don't listen to my thoughts in the first paragraph :)
An amazing entry overall :)
