'Tis great!
When I saw "rhythm" in the title, I was expecting something along the lines of SCGMD, but it turned out to be even better
The art in this game is spectacular, and it is very fun to see all the levels and try to guess what will fall on you with the next beat of a drum. The save eggs are another excellent touch, avoiding the situation in other games like this of trying to reach a set checkpoint over and over.
I really don't mind the slippery controls. Without them, the game would be too easy to be fun. Managing your momentum is the whole point of this game.
The only thing I have a problem with is the final boss battle and the save eggs being disabled. The level before, which the game keeps restarting me to, is very easy and relatively short, but that doesn't mean I like to do it over and over again before getting one more crack at the wizard.
