This is just an updated demo. I fixed some of the errors in V0.2.03 and added new code to improve it a little.
When you pop a bubble you score points and XP, the currency of the game which you will use to buy upgrades and patches. Now you can also string together combos, meaning popping more then one bubble in a row. This lets you earn more XP faster, but don't miss a bubble or you lose XP. The Combos also let you score more for every bubble you pop. You'll be able to save your game and continue at a later time if you want.
You can upgrade your pea shooter by buying upgrades and patches from the weapons shop. Some upgrades and patches will have an achievement requirement. So in order to buy it you first need to unlock that achievement.
Some achievements will be real easy to unlock and some will be damn near impossible. One of the hard ones will let you buy a laser cannon and it's upgrades and patches will all have achievement requirements.
Levels and Rounds
You progress through the game by completing a set number of rounds on each level. Each Level gets progressively harder to complete. And each completed Level unlocks an end of Level Achievement which unlock new upgrades and patches. I plan on adding around 10 Levels with about 5 to 8 rounds each.
Now just because I've made it opensource doesn't mean every one can just hop on to the band wagon do what every they will. No I'm in charge of this project. If you want to know more then checkout the web site. I've set up a new site just for bubble buster. It's not much but I'll add to it as time goes by.
