I really liked the game but it is too easy. Purple, green and red potions are too powerful for how often you actually get them, heart droprate is too high and maybe later enemies should deal more damage.
Get Laser Link, BFG and Duck Death. Avoid getting hit while firing Duck Death and Laser Link as often as possible. BFG ist a bit more difficult to use but if you fire it in his path the right way it´ll do tons of damage.
Doom them all isn´t that difficult, but why does "rack up the points" end so quickly and why do i need to play the lessons again if i want to play it...
Nicely done game with a rather old concept, it gets quite impossible to survive the later stages of the game when the new lines appear quickly. If you could make it possible to pop a new group of stones before falling ones have settled in place that would be remedied.
a bit too easy, you can beat almost the whole game by sitting in the middle and periodically pressing "2".
an explanation for the "Option" button would be nice, i only found out that it`s an upgrade when i wanted to pause the game.
an last a MUTE BUTTON!

Pro:
Nice graphics
leveldesign seems to be OK
a lot of upgrades
Contra:
horrible Control (my finger hurts...)
Sound gets on you nerves almost instantly
the only way to win is to constantly star fail-saves, and if you do that its way too easy
That´s the beauty of this game BluesDrive there are multiple Differences per level and every time you play others will be in the picture. great replayability
