~Homebrew~ Crypt Sweeper (GBA) - RetroAchievements/guides GitHub Wiki

Any additional info or correction can be sent to me in a DM to my RA account or the email on my RA motto.

This game is an interesting version of Minesweeper, instead of needing to mark all mines, your only goal is to defeat Death, and for that you will need 13 HP available.

How to play

Action Buttons
Move D-pad
Select/Attack Monster/Collect Exp A
Mark Tile B
Level Up Select
See Inventory Start

Select uncovered tiles (green) to find out what they are hiding, only 1 at the time, even if they have nothing under them. Empty tiles will show how many mines are in the 3x3 area around them using red squares, and the number is the sum of the Lvs of all monsters in the same area.

If you uncover a monster, you will fight it, if you have more HP than their Lv, you will kill it and you can pick the EXP, as much EXP as their Lv, but if you don't have enough HP, is Game over, having 0 HP isn't a Game over.

Books

Credits to Moka for finding this.

You can get a book after winning a level, but only 1 at the time, you get one the first time you beat a level in each difficulty, and from there you have a 50% chance of getting a book if you meet it's conditions.

Most Monster books can be obtained by leaving their EXP on the level when you go trough the door, the next table will only list the Monster books that have other unlock requirements.

A tip for monster books: At least for me, using EXP from chests to level up and heal instead of using hearts let me save 1 heart, letting me heal after killing Death, now you can kill the enemy you want and not pick their EXP to unlock the corresponding book.
