Abyss Odyssey

- Trap enemies in corners to demolish them, this works really well with the first character's rapid special.

- Monster souls are extra characters you can flip between with your main character. HP is remembered for each character when you swap. Don't forget to use them if things get hairy

- The black and white stages are chances for you to get a monster soul for free; if you win the black and white stage, you get that monster's soul. If you had one already, it swaps out and you can swap it back in if you liked your old one more.

- You can only hold so many potions, so choose carefully or use stuff when you find new potions

- To unlock the third character, you need to go to the middle middle room and donate a bunch of money

- You can buy camp tokens and set them in those hero altar things to set a respawn point for when you die. Better tokens let you respawn more times.
