I loved the original 5 differences. This is pretty good too. The graphics have been amped up quite a bit, but the difficulty curve flails around a bit during the levels. You don't REALLY have to click all 6 differences if you don't want to, since pressing H gets rid of one of them instantly, albiet at the cost of satisfaction of completing the level. Plus, when I saw where the difference was, I almost always felt like an idiot. That's not a complaint, mind you. Nice effort! 4.5/5
I'll keep it simple...
+I like the 1234 idea, when using the keyboard as a guitar..
+Nice upgrade of graphics!
+ALMOST NO LAG! Haha...
-Yes, bring back the old voice.
-I like the stickman picking the individual notes, but... No fire? I liked the fire!
-None of the improvements mean anything if the songs aren't any good. It's hit-and-miss, these songs are.
For those of you who think it's hard...
YOU HAVE BEEN WARNED!
After a certain level, the lag completely murders whatever fun I could be having. This game killed my guy far too often because he wouldn't jump if I put a blue whale on the space bar.
