Physics bouncing can be unpredictable, and i noticed that merging bubbles depends on bounce angles and timing, which sometimes makes gameplay frustrating but addictive.
Moving to aim and shoot bubbles, then you'll quickly learn the game mechanics like merging numbers and clearing obstacles, which is kinda weird anyway, as physics can surprise you.
Inside the game, you click or tap to aim and shoot bubbles, which is simple, but their physics sometimes bounce unpredictably, making level management tricky, especially in tight spots.
Quick tips: aim carefully, then plan shots to bounce bubbles off walls, which i found helps clear tricky sections, especially the ones with obstacles or tricky physics.
Physics stuff play a big role, and merging bubbles relies on bounce physics and timing, so managing shots and predicting bounce angles helps you win, even if it feels wonky sometimes.
