Nice, but major bug issues
As has been said already, you can win after just two minigames, and the GBA minigame is really wonky. My guess is that you have it prevent you from moving into a wall by simply cancelling the movement if there's a collision, when instead you should be moving the red block so they're just touching the wall (it's pretty easy to calculate, especially when all the blocks are the same width like this). With the falling object minigame, the hit area was big and took the fun out of it. If you're using hitTest just use a nested 'hit' movieclip, or if you're using custom collision detection, use a smaller rectangle.
Still it's got a nice feel to it, and it was clearly made with clockday love, so I voted with clockday love.
