Very solid puzzle/platformer, but the glaring problem I see is the inability to see the level(or even where you are going) in advance, adding an unneccesary trial and error aspect to the game.
Not as good as it's predecessor. The fun of upgrading your tanks is ruined by how long it takes to improve your tank and how slowly you accumulate gun points. All that's left is the tedium of slaughtering Bubble Tanks over and over. The previous games weren't challenging, but they were interesting, this one lost that touch.
My biggest annoyance with this game is if you accidentally click retry after finally completing a tough level, YOU HAVE TO START ALL OVER AGAIN with no way to advance! It's a hair-pulling frustration.
Can you PM what's happening and what Flash version you're running?
