🕳️ Abyss Brawl: 18 FloorsPlay
Abyss Brawl: 18 Floors is a pixel arcade about descending a bottomless shaft. You hop down from platform to platform: solid, crumbling and moving ones, springs and conveyor belts change without warning, and hearts, shields and poison fruit hang between them. The run score is the depth itself: one metre down is ten points.
Four computer rivals descend beside you, shove, punch and grab the pickups first. There is an easy descent, a normal run and a Mayhem setting, and solo practice leaves the shaft to you alone. The five heroes have moves of their own, so the route depends on more than the platforms.
After the thirty-sixth floor the game switches to a side-scrolling arena: the boss has several attacks, and you get a light and a heavy strike, bombs and cannon shots. Beyond that lies a campaign of eighty-one trials across nine lands — six narrow paths, two elite guards and one boss each.
Game modes
Classic
A normal run: four computer rivals and medium difficulty. They descend beside you, shove and fight over platforms while you find your own route down.
Play →Easy Descent
The same four computer rivals on easy difficulty: wider platforms, lower speed and rivals that attack less often. For a first look at the game.
Play →Mayhem
Four computer rivals on hard difficulty: a faster descent, narrower platforms and rivals that attack on purpose. For players who already know where to catch a heart.
Play →Solo Practice
A descent with no computers: only you, the platforms and the depth. Learn the routes, springs and bosses at your own pace, and the run score still goes to your account.

PlayHow to play
- Pick a hero. The lobby offers a hero you can keep or rebuild: the five characters differ in their moves and speed, and the name and look are set before the run.
- Start the descent. The start button launches a run against four computers. Difficulty is picked right there, and the solo button removes the rivals and leaves you alone.
- Stay on the platforms. Space jumps and S drops you through a platform. Springs, moving slabs and conveyor belts wait below, and the danger line presses from above: standing still is not an option.
- Collect the pickups. A heart adds a spare life, up to three in total; a shield absorbs one hit, and poison fruit takes a life. Pickups hang on platforms, so you have to reach them in time.
- Fight the boss. In the arena the light and heavy strike, bombs and cannon shots do the work. Winning opens the next land of the campaign, and R claims the boss reward.

FAQ
Do I need to install anything or sign up?
No: the game opens in your browser on the portal page. A Levbee account is optional — as a guest your best score stays in the browser; sign in and your score, records and achievements live in your profile.
Can I play online or with a friend?
No. The portal build is offline only: a run against four computers or solo practice. There are no rooms, no invite links and no shared runs in it.
How is the score counted?
The score is the depth: one metre down is ten points. The portal accepts up to 50,000 points per run, that is five kilometres; the server decides whether it is a record, not the client.
What do I play it with?
A keyboard: A and D, space and S. The game is made for a computer with a large screen — it is awkward on a phone, and we will not pretend there is a mobile version.
What happens if I fall?
With lives left you come back on a safe platform after a fall. Once the lives are gone the run ends and the result screen shows your metres, points and place among the rivals.
