I have to say this was pathetically easy... but fun until I figured out what the strategy was. Like pretty much everyone else now that I read the comments haha. Spam roadstars, then spam Razzo, then spam schnells... if you want to make points intentionally get a lot home and then loop the arrows. As soon as it starts to get nasty just scoot one home and you win ay?
sorry... I'm not usually like this.. but if I wanted to play guitar (without actually having a guitar) I'd sooo play the wii guitar hero or even the playstation... this is just horrible
if your having trouble getting the last achievement just do another level (I did level 1 and got the 'perfect') and it then triggers the 15 achievements badge.
