This doesn't seem to have changed at all from the console versions including labelling buttons as Z, Y, B and A. The graphics are very colourfull and so fast you barely have time to notice much else - but it does seem to be quite simply textured for the main part.
Switching between the 3 heroes on the fly is still confusing as the game runs so fast that you barely have time to look at the indicator to decide which one you want to tag in next. This also means that although it is essentially a very simple kids game the added control difficulty means it's probably aimed at 7-8 year olds.
This seems a bit of a shame as my 4 year old can do the running about bits!
