Right, time to write a review that's helpfull
Firstly i will say that i really like the style of the game, really fun and the comments at the end of a level or set i should say :P were pretty funny.
As stated below the levels were pretty easy, perhaps you could have taken away the line that shows where your bullet was going either completely or partially, maybe both as you get later on in the levels.
What got me at first was sometimes you weren't allowed to change your characters position until you hit a balloon with the icon on, it didn't take long for me to work it out but in the first level that featured moving your characters posistion i didn't have to do that so i presumed that would always be the case. for a future game if a tutorial isn't made perhaps just a page with all the balloons you can get on levels with descriptions on what they provide.
Over all i would reccomend this game, there wasn't any bugs that i found and the music which is looped didn't get on my nerves and suited the style of the game very well
