Ok... A little bit or now.
So far Ive played through Level 1-6.
The first few levels are extremly easy...just kinda getting you into the mix.
The game feels alot like Yoshi's Island, with a bit of Super Mario World thrown in the mix.
Peach can attach enimies with her umbrella, as well as picking them up to through at 'purses' to get some coins/hearts. The game has a bit of a puzzle feel to it as through some stages you are made to remember colors of mushrooms and only hit the same color flowers in the next part of the level.
Most of you know, Peach has emotions.
The one I have used the most is the 'green' one with makes Peach cry. Her cryings allows her to water flowers and have them grow (Much like in Yoshis Island) to allow her to finsih a level or collect a toad (3 in each level are trapped). This emotion also allows her to rn really fast, so she can cross bridges that collapse to easily.
The second emotion is 'red' which is Fire. It makes Peach really angry, angry enough to burn down bridges.
The third emotion is...yellow I think. This gives her a forcefield I beleive (never used it)
The fourth is orange which allows Peach to fly.
Like I said above, each level has 3 toads you must get. Sometimes you can get them right away, sometimes not until you have new moves. Yes, you get new moves. With the coins you collect you can purchase a few new moves, as well as other things (Its in japanese...Im unsure).
The first bos level takes advantage of the stylus and acts alot like the Mini-game in Super Mario 64 DS where you fling Mario into th sky. Really awesome.
Alright, thats it. I'll post a bit more later, right now Im extremtly tired and hopefully this impressions makes sense.
