A nice wholesome storyline to wrap up a series of minigames, with a cute art style, I like it! A bit of explanation of what some of the minigames would be exactly like needed to reach the HD, as I'm left wondering the scope and difficulty to implement of each of the games. While this concept leaves you open to doing lots of different ideas, you will need to be careful of how many minigames you attempt to do. If the minigames are varied, this increases your workload as you have to build multiple control schemes and styles. Unless they're similar or all based upon the same core mechanics you've already implemented like the topdown movement.
