Heres an update to the game.
puzzle bubble Beta 2
Unfortunately i haven't had a lot of time to construct, but i'm still slowly plugging away.
Small list of changes:
-Play area widened to allow greater variety of level / puzzle designs. (may get bigger when i eventually change game to a 16:9 aspect ratio)
-power ups are now solid like bubbles (before you could pass through them but i decided i didn't like this).
-Started work on some temp animations and effects to integrate the code into the engine, but still no graphics or sound.
-levels now progress automatically if you win or reset if you loose. Still only 5 test levels so far.
-new pointy arrow, but does not show rebound angles (need power up for that).
-rows drop down at different intervals depending on level now. The idea being on later levels they drop quicker to make the game harder.
Will probably add score next.
