NOTE: THERE ARE MASSIVE SPOILERS FOR THIS GAME HERE. DELETE THIS WHEN YOU HAVE A SPOILER TEXT-BOX.
This game has a crapton of bonus content, and I believe you all know this. No matter how long you play, there's still something lurking in the shadows to appear and say "You still have this to do".
So, here, we will talk a little about this endless bonus content.
Conglaturation! This story is happy end! Being the brave and coura- *hack* *cough*
Anyways, you broke the fifth wall, saved the world from being dominated and shtuff. But there's one thing you should have expected. There are MORE walls... They are called Bonus Walls, and they are slightly pattern-based. The first bonus wall(Called Bonus Wall #9) needs twice the wall damage the final wall does, needing a total of 200 Quintillion Wall Damage. The second bonus wall(Called Bonus Wall #8) needs twice the wall damage the first bonus wall does, needing a total of 400 Quintillion wall damage, and so on so forth until the ninth(Called Bonus Wall #1).
But... IT'S A TRAP! Now you triggered the Boss Bonus Wall, which needs 2.9296875 times the wall damage as the ninth Bonus Wall... Which means the ninth wall needs 51.2 Sextillion and the boss wall needs 150 Sextillion damage.
So... You defeated the almighty Boss Bonus Wall, and got a Boss Point! Hooray!
Yes. When you defeat the Boss Bonus Wall... You have ten Space Walls to defeat! The first Space Wall is 2 1/3 times stronger than the Boss Bonus Wall.
Then, the pattern i just said repeats. The Boss Space Wall has a whopping 300 SEPTILLION Wall Damage. And that's still NOT IT!
