I played this twice through before I realized he was picking stuff up in the basement. I thought it was supposed to be some artsy thing where the basement was the end. The actual end was far superior, if still artsy.
You can get 4 stars on each by experimenting with how the planes turn in the beginning. Sometimes the difference is a long 90% or a short 90% turn. With dusters, the AI is bad, slow down a little and then start dusting with your planes in a horizontal line formation. All the slow planes, just come in behind them at 30 degree angles and slow down before peeling off the attack before you get within half a grid square. The balloons have a short range, so approach slow and turn around or peel off.
There's a bug which makes the plane drop pineapples twice as fast in fast forward mode and at a normal rate otherwise. Look at the spacing of the pineapples at the top level plane on fast forward and without.
Put the flat blocks under each pair of mines so they slam to the ground. Then the square falls easily and the red one you use the far upper left mine to shoot it at the mine on the right side which stops it on the burger.
This game is excellent. I had none of the issues the other people mentioned as far as controls. The idea is novel (Anti-Kirby inspired maybe?) and the difficulty is just right.
