I love this type of 3-match, upscrolling game (planet puzzle league [DS] is my favorite) but this one is done all wrong, the line jumps when a new line scrolls up, making it almost impossible to play. The stacks collapse instantly, without giving time to setup a combo.
I got frustrated during the scanner boss and tried to give up! I found this out though: when you respawn, fly right INSIDE the boss body, your temporary invincibility will last the rest of the fight. (which will be a long time since all you can damage him with is your basic pea shooter)
not a bad puzzler, but it seems like the kind where I won'g ever beat the score I got my first game, as looking to set up combos is no more effective than clicking the first pair you see.
needs a gimmick.
timer? limited moves? fixed obstacles? but all of that would take away from the fun part: completing it whatever way you want. I'm torn, rated it 4/5.
