1. Each character possesses distinct abilities. Carefully reviewing character descriptions before commencing play will aid in quickly understanding each character‘s role. 2. Beyond defeating enemies， prioritise destroying structures whenever possible. This is the primary method for achieving star ratings upon clearing levels； the more buildings destroyed， the higher the rating attained. 3. Additional skills can be purchased in the shop. When facing excessively difficult levels， consider acquiring powerful abilities to aid your progress. 4. Pay attention to the characters‘ attack sequence. Plan each character‘s target in advance and strategically utilise their skills to clear levels. e.g.: Level 16 Note the left-side units: ROCKETOO*5 and CAPTAIN JOE*1. Utilise ROCKETOO‘s ability to rapidly descend mid-flight to demolish overhead structures. Prioritise eliminating left-side and central enemies. Due to trajectory limitations and skill constraints， CAPTAIN JOE can scarcely engage left-side or central foes； reserve the right-side enemies for him.
