Added a level title to the game. (ignore the title text, i've just named the levels after fruit for now).
I've also been thinking about the games theme. I've decided to go with a fantasy one. The bubbles will be different monsters, and the main character, currently the arrow, will be a monster hunter...or something.
I've changed the bubble image. It also helps me visually track whats happening with animations, as for example their facial expression will change on collision with wall etc.
I'm also working on a proper level structure. There will be 5 rounds to each level, with each new level introducing a new power up or hazard to the game. It will also feature different enemy and background graphics. You'll also be taken to a map screen at the end of the 5 round to track your progress through the game as is now standard in casual games.
Current version can be player HERE.
