Vampire Survivors

Pick the character with the most life points, I recommend Red Death (it's isn't achievement related but it is one of the strongest characters in game. It has 334 HP points and +112% speed default, and if you have hollow heart it goes all the way up to 851 HP points). It's useful for the end of the level (18:00 - 20:00) because of the cubes trying to kill you and you won't be able to kill them no matter how strong your setup/character is, and due to that, a lot of HP chickens spawns around you, and follow the map on the pause menu to get them or else you'll die. and if you do I recommend having bought the Respawn (Tiragisú) upgrade on the main menu so you can respawn.

To unlock space 54 you need to have gotten 5 golden fingers on previous levels. For that I recommend playing the Astral Stair level for that. I explained better that on my solution for the other achievement.

After you've entered the level and if you've unlocked Randomazzo, choose the VIII card (the one that looks like a tree with a green background). If you've unlocked it. It will attract the Empty tombs and the candelabradors, then choose the following weapons/passives below:

Weapons: Water - Bible - Axe - Knife. The other 2 weapons are on your choice.

Passive: Attractorb (Evolves water) - Spellbinder (Evolves bible) - Candelabrador (evolves Axe) - Bracer (Evolves Knife) - Empty Tomb - Hollow Heart (Important, since you need as much HP points as you can).

If you have the chance try to evolve first the water and bible and then the axe and the knife.

Once the 20 minute mark has been passed you’ll beat the level and this achievement will pop
