GOOD: Level design is well done. Graphics are simple but to the point, and the controls work pretty well. The tutorial levels are a nice touch that a few game makers completely overlook. And the quick tips in the beginning of levels are good.
BAD: As said in other posters the stars are extremely touchy and you need a fast hand to match some shots. I found that I've had to solve many levels in different ways then they appear to be designed due to difficulty. The first few tutorial levels are good, but after that it just seems like you didn't put thought into the order of levels. I had a few that were really tough, and then easy and then tough ones after that. The music gets annoying after about 10 levels. The quick tips at the beginning of levels block the screen and I found myself clicking to get rid of them only to have my rocket fly away. When you fly off the map you have to manually restart even though you're out of gas and not moving.
Other stuff: It felt displaced with it being space but having air resistance. Sometimes my ship would stall and just slowly coast in a semi-random direction which was really bizarre. The actual game area is very cramped. Maybe the ships/bombs/moon should have been smaller to make it feel less cramped.
