Bright star-themed slide puzzle game with warm yellow star background and wooden labyrinth track maps. Slide colored jelly cubes (yellow, orange, blue) along closed wooden corridors, gather all cubes of the same color into one stack to trigger merge elimination, earn score points before the countdown timer hits zero and clear progressive difficulty levels.

Core Slide & Merge Gameplay Rules:
1. Track Physics Control: All jelly cubes slide continuously along the wooden maze corridor until hitting a wall or another cube. Swipe screen left/right/up/down to shift the entire cube group in the target direction.
2. Same-Color Merge Elimination: When 2 or more identical colored cubes collide and stack together, they instantly disappear and add points to your SCORE counter.
- Orange cubes: Basic low-point elimination unit
- Blue cubes: Medium-value merge target
- Yellow cubes: High-score jelly cube
3. Countdown Timer Mechanic: Every level carries a limited TIMER countdown; you must eliminate all colored cubes before time runs out to pass the stage. If the timer hits zero with leftover cubes, the level fails.

Progressive Level Difficulty Design:
- Level 1 (Cross Maze): Symmetric cross-shaped wooden track, only orange + blue + yellow cubes. Two orange cubes start on separate top corners, slide them down to the bottom central channel to merge and eliminate, simple single-color matching for beginners.
- Level 2 (L-Shape Irregular Maze): Asymmetric stepped corridor layout with an internal small blocking wall. Mixed three-color cube groups scattered in separated track zones; players need to slide cubes around the central obstacle to gather same-color blocks for merging, testing directional slide planning.
- Level 3 (Double Zigzag Maze): Double S-shaped symmetric track with two central fixed wooden barrier blocks. Only blue and orange cubes appear, split into left/right isolated zones at the map top; slide down to the bottom central passage to combine and eliminate all matching pairs, requiring precise sequential sliding order.
