Overall fantastic work, but a few hiccups,
After waiting for so long for SCGMD4 to come out, I can't say I didn't give a squeal of delight when I saw it on the front page. However, I have to say that this isn't as much a mind-blowing game as much as the last two were. I have only a few reservations about this game, but it's a shame that such little things ruin an otherwise awesome game. First, I think that there's a slight timing issue because some notes come a bit too early and others come a bit too late, which makes it that bit more frustrating trying to get things perfect.
Secondly, there are too many distractions, the little guy at the bottom of the screen and having the numbers and the arrows the same colour is extremely confusing! If I don't get distracted by that little bloke, I keep wanting to press "up" instead of 4 or "down" instead of 1, etc. I think that an option to turn the colours of the numbers back to silver/grey would greatly improve this, and maybe a little reward video for completing all the songs could be the animation of the stick guy running, surfing, flying, etc. like he would do if you were playing?
One last thing I miss is showing the length of the song before you play it, along with the timer bar across the top. I know that there's the star scale showing how well you're playing (great feature in itself btw), but it's just not the same!
On the better side, I think all the other new features are brilliant! Especially the boss battles and new instruments, even more so a medal/achievement system!
Thank you for taking the time to read this if you got this far, I appreciate it :)
Much love and (despite the odd setbacks) overall fantastic work!!
