the computer cheats. you should put a limit on the amount of extra moves it is allowed to have.
I love this game, although it's a bit short, you should do a second part!
your description is completely wrong!
There aren't any minigames, there are only TWO ships, and there are not even close to 50 levels.
It seems the CPU opponent cheats a bit..
After playing through a bit, I started to notice that things just weren't looking right. THe computer was getting 4 and 5 matches for extra turn repeatedly, even when I watched it only match 3 icons together, and only those three dissapeared. I even watched it get a match 3 with 2 icons. So it gets a bit pointless when it starts to seem like the reason you're having trouble isn't because your eyes aren't finding things right, but the computer is using it's own set of rules.
just like puzzle quest only boats I like it but the computer is weird. It will ignore 4 in a row for a 3 yet then the falling blocks would either do a 4-5 or in some cases a flaming block.
