Count from the actual appearance
Ninja Drop asks players to drop a shuriken to pop incoming balls. It also warns that a bomb explodes in three turns once it appears. That makes the bomb a deadline rather than just another visual object. When one is introduced, observe how the game marks its appearance and counts a turn. The record does not define that accounting, so do not assume an animation or a missed input consumes time in the same way.
Reorder the next decision
Before the bomb appears, a route through ordinary balls may look attractive. Its appearance gives you a reason to reconsider that plan. The supplier urges eliminating it quickly, but does not explain whether a direct hit is required or which interactions can remove it. Read the actual feedback and choose the action that addresses the bomb under those rules, rather than continuing an earlier target sequence automatically.
Learn drop behavior separately
Mouse and touch are listed without specifying how position or direction is chosen. Establish the shuriken's actual drop behavior before relying on a complicated prediction. A useful early exercise is to connect a chosen drop location with the result, then apply that knowledge to a bomb deadline. After an explosion, review both turn counting and target selection instead of assuming the only problem was insufficient speed.
