Bust-A-Move 4 is the fourth installment in the Bust-a-Move series. It can be played on Arcade, Playstation, Dreamcast, and Gameboy Color.
The story from the North American Dreamcast booklet. It's called "A Bedtime Story".
"A peaceful day ends with a wild night when a character is awoken from a visit from Cronoa, Governess of the Future. She comes to warn you of a dire situation, and to ask your help. The Arcana, mystical cards, have fallen into dimensional cracks we call dreams. The energy of each card will be out of balance unless someone brave and skillful can enter the dream world and seal each card. Each card has five challenging puzzles which must be solved in order to seal the card. It won't be easy, but Cronoa- and the whole universe- are counting on you to see this difficult task through the end! If you mean this challenge, you will be greatly rewarded. Do your best to burst the bubbles and seal the cards!"
There are several different modes you can play in.
In Arcade you can do three different difficulties: easy, normal, and expert. You go through 5 levels per letter. After you beat those 5 stages you can move further up to another letter. When you get to the end, you'll get to see a picture with a few characters interacting. The ending pictures differ depending on who you play as.
In Story mode the goal is to seal the Arcana, mystical cards, Cronoa has lost in the dream world. You select different levels based on Tarot cards and play through 5 at a time. After you beat and seal a card, more will appear. Once all the cards have been sealed you will be able to do a Tarot card reading.
In Collection you can play on different levels at your own leisure. There are many levels to choose from.
