I couldn't figure out how to attack/defend a city. This game needs better instructions. Also the road travel although interesting at first becomes very monotonous you need to be able to set some of that stuff on auto pilot or make it more interesting.
Yes the sound is a bit annoying but you can just turn it down.
The main problem I had is that the female, who carries the next ball to be played, holds the ball up higher than the on in play currently. In addition, the one she holds is larger then the one currently in play. This causes me to often missthrow because I mistake hers for the one being fired.
Other than that, very interesting rendition of bubble bobble.
This game has huge problems with the ability to control your character. I'm not sure what seems to be the direct issue but the ship seems to like to continue to move in the direction of the last key pressed and then doesn't respond to any new key presses. This looks to be a coding issue where a "Key up" event isn't registered properly and you ultimately lose the ability to control your ship.
Please provide more robust coding for the directional controls.
