I wanna go across the Rainbow
-Red features basic platforming, and serves as an introduction to the game
-Orange lets you show off by taking shortcuts through some jumps requiring above-average skill
-Yellow tries to trick you with traps that fire off without warning
-Green takes it up a notch with tight gaps and tricky segments
-Blue adds some variety by replacing spikes with apples
-Indigo is well known for the infamous 'Ding' blocks which appear in the last place you'd expect them
-Violet is all about moving spikes, my personal favorite area
If you don't get the secrets, you'll face a troll boss here and that's the end. But I highly recommend you find the secrets - this game really shines in the 100% category. You'll be treated to a final medley area of all the previous gimmicks, before reaching the Ultimate Madoka - a gruelingly slow paced boss, which will drive you crazy your first playthrough.
In all, I highly recommend this game, it's a great intro for new players and promises fun every time you replay it - and is great for speedruns!
A classic everyone should play.
+Music is good
+Platforming is nice, traps are tasteful
-No pot of gold at the end :(
