On Hard for levels 13, 33, 35, 36, 47, balerion, and haku are the only ones with no way to win. All but one of the above are 75% enemies to get a star. I have played so much i have the highest maxed out plane, pilots, and bombs. I count how many objects are seen in a round and lay it to waste- worms, missiles, and any enemies. I have maybe 2 objects escaped as the rounds are memorized… well above 75%. In round 13 i scored 13,000,000 points and still have not enough for 75%. On level 47 chase i have verified i am getting all the coins. I even sweep to the edges to die looking for some “random coin” that might be off the screen- it doesn’t exist. I used the damage magnet item to help look for it. No joy. Balerion I got all the coins and none of the awards paid out. Haku literally has no win as you can’t possibly get all the coins even if you play perfectly (big long wall where coins would not be reachable. Please fix these levels!
