Known Bug: Some additional Hives are randomly generated and there's the possibility you could get some placements you can't reach. If you encounter this please give the game another go as its RNG for a few extra spawns. It shouldn't impact every run.  Thanks

Walkthrough

About

20 Floors was made for the GMTK 2026 Game Jam. The theme was 'Countdown', I thought about elevators counting up and down floors. I decided to create a game about descending floors and having a limited time on each floor before the elevator goes without you. You must purge each floor of all enemy hives before delving down further.

*Stretch goals - I intended to have the tether controllable to be able to swap between it providing you health, ammo etc. I also wanted to have a boss on the last floor but due to time constraints and procrastination I was unable to get those added. I'd like to have made each floor get gradually more cursed as you descend and have more floors/randomness.

Destroy All Hives

To beat a floor you must first destroy all hives before tethering back to the lift.

Monsters

The Drone is the most common enemy and slowly seeks out the player, they can be avoided for the most part.

The Brute is fast and tries to get in your face, if you can't shoot him back, avoid him or knock him back with your baseball bat.

Weapons

The Melee attack is great for knocking back foes and saving ammo. The pistol has unlimited ammo, the rifle has great fire rate, and the shotgun has spread.

Random Generation

In the current version there are 12 floors that can be randomly selected, additional loot, enemy and hive spawns can also occur.

Rarity

A weapon rarity system ensures you continue to get stronger as you delve deeper. If a weapon is in your inventory and a duplicate spawns on the next floor its rarity will be higher than your current weapon. Rarity increases the fire rate of the weapon, if you swap to a new primary weapon you will lose progress on your current rarity for that weapon as you drop it on the floor. You can tell what rarity an item is by its coloured outline.

• Common (white) 
• Uncommon (green)
• Rare (blue)
• Epic (purple)
• Legendary (yellow)

Low on Ammo? Tether Kills

Tether kills can be done by saving enemies in line of your tether when you finish a floor rather than defeating every enemy. Each tether kill grants you 5 ammo and for every 5 tether kills you get one heart of health replenished

Beat Floor 20!

Beat 20 floors and you win the game, good luck!

Game Over

If you run out of time clearing hives or take too much damage you'll get a game over
