Ravva and the Phantom Library (UP)

This is Book 0 (green book) at the main menu.

There are 4 challenges:
- Find all 200 coins.
- Kill all 15 enemies
- Revel and destroy all 40 pumpkin blocks
- Find 6 secrets

You can check your progress by pressing in the level. If you complete one of the challenges, it will stay completed, next time you start the level, but progress isn't saved if you don't fully complete the challenge. So you can't collect 190 coins on 1 run, complete the level, and then restart the level to collect the remaining 10 coins, it will restart at 0.
Keep the orange bat equipped and spam as you move throughout the level, you shouldn't have any issues if you are taking your time and checking everything. Secret areas will give off a shiny blink. Check every block and make sure it's not a pumpkin.

Lordacris Gaming has a walkthrough of the level if you are having trouble finding everything, this level starts at 1 minute.
