Bubble Trouble

Bubble Trouble is a highly relaxing 2D arcade-style game. You need to pop all bubbles appearing in the game. These seemingly fun bubbles are actually dangerous as they bounce around the scene, and you must dodge nimbly. Grab your gear and start an exciting bubble-popping challenge.

The core goal of Bubble Trouble is to dodge collisions from bouncing bubbles and shoot down all bubbles in the level with your gear within the time limit. Players challenge progressively harder levels, where initial bubbles split more times. Complete all levels with agile movement and precise shooting.

• The game features progressive level design with increasing difficulty as you advance. Each level spawns bouncing bubbles, and you must eliminate all bubbles before the timer runs out to clear the stage and unlock the next one automatically.
• Bubble splitting rule: Shot bubbles split into smaller ones, with larger bubbles splitting more times. Only when bubbles shrink to their smallest size will they burst completely upon being shot again.
• Level failure rule: Contact with any bubble instantly resets the current level.
• Two-player mode rule: The game supports two-player gameplay with fully customizable keyboard controls. Both players must cooperate to dodge bubbles and shoot together to complete level challenges.

Game Controls

• Single-player controls: Move left with the left arrow key and right with the right arrow key by default, press spacebar to fire. All keyboard controls are fully customizable. You can also switch to mouse control in settings, move your mouse to control the character's position, and click the left mouse button to fire.
• Two-player controls: Both players can fully customize their keyboard controls, choosing any key combinations for movement and shooting that feel comfortable.

Do I have to eliminate all bubbles before the timer runs out to clear a level?

Yes. Each level has a fixed time limit. You can only clear the level successfully and enter the next one by popping all bubbles before the timer expires.

What determines the number of bubble splits?

The number of bubble splits depends on the initial size. Higher game levels spawn larger initial bubbles, which split more times and require more shots to eliminate completely.

Are the controls the same for two-player mode and single-player mode?

No. Single-player mode supports mouse control and fully customizable keyboard keys. Two-player mode features completely independent key settings without being restricted by single-player binds, allowing both players to choose comfortable key combinations based on personal habits.

What happens if I get hit by a bubble?

Getting hit by a bubble will restart the current level immediately. Accumulate a certain number of hits, and you will have to restart the challenge from the first level.
