This is pretty much just a finished game.
I love how you structured the game out of a series of simple mini-games, it felt very dream-like and they were a lot of fun too! Art, writing, music and even sound effects were all gorgeous (I particularly like how well the "jump" sound goes with the music for that jumping minigame), the whole thing just has a very professional, polished sheen to it. It's the little details that count, like Marisa blinking on the title screen.
With the inclusion of optional side-modes too, this game is a marvellous example of something that makes a lot out of a little. I'm thoroughly impressed!
