good idea
Good idea but it needs some work. First and foremost the power bar; it really doesn't deliver the punch it promises. I have a good sized (like 10cm) power and the ship hops like 5 pixels forward. It's confusing, you can get used to it yes, but not many people will give your game a chance if they are annoyed by it. I didn't really find much need to use the lower power levels anyway. When do you ever need to hop couple of pixels forward? Played 16 levels and the answer is never.
That brings me to level 16. Is that level even beatable? The ship just bounces backwards from the blue cubes and always dies. I tried it several times thinking maybe I just need to come in a good angle, and that probably is the solution but god damn you must have made it that you need the perfect angle and with the launching being what it is, it's way too hard to hit it.
I liked the pixel graphics and the music fit the game, but work on the playability and level design.
