Gravity is the main thing. The ball falls down fast and you must slide it on platforms to slow the descent. I noticed that if you keep it still too long you lose it, and hitting the top ends the run. Slope platforms speed it up and you must react quick.
Click and slide to move the ball across platforms, trying to keep it from hitting the bottom. You guide it on surfaces that help or hurt the fall, and some have slopes that boost speed. Avoid staying still, watch the top, and time slides to slow descent, then you last longer. The controls are simple taps and swipes, and the goal is to survive each level by steering the ball carefully.
Often i try to play it on my phone, and the controls feel like sliding a finger to steer the ball. You tap to move, you swipe to slide, and you release to let it drop. The platforms change, and some slopes make it go faster, which is kinda weird anyway, but their main job is to slow the fall. If you keep the ball still on a platform too long, you lose it, and if it hits the top, it is over.
Quick tip from me: i found that sliding the ball on platforms at a steady pace keeps it from falling too fast. Use the slopes to gain speed only when needed, then slow down by staying on flat parts. Avoid staying still for long or you will lose the ball, and keep an eye on the top to avoid a game over. The trick is to balance speed and control, and i learned this after a few tries.
Stamina is the key word. You slide the ball on platforms to slow its fall, and staying still too long makes you lose it. The top is a danger zone, and hitting it ends the run. Slope platforms speed things up, so you need quick reflexes and smart moves. Use your finger to slide and tap, and keep the ball moving to avoid drops. The goal is to guide it safely to the bottom without hitting the top or staying still. It is a simple thingy but requires focus and timing.
