I started playing yesterday, have more than 3 hours of gameplay and it didnt give me any achievements and I'm sure I've already did things to get at least one.

I really like this so far. ( although I've only played about 30 minutes ) Tough yet fair. Does anyone know approx game length?

I get to the top of the tower, and there's a gate there with a switch on the other side. i do not see any pressure plates or anything around. What is it that I'm missing?

the art looks nice, but everythign is kinda small ish ( i have terrible eyesight ) how does thi splay out? Is it like The Lost Vikings, where you need to constantly swap heroes to use the appropriate powers for level puzzles?

I went to all the maps, broke all the red boxes, and got achievements. all that while, I used Marman Song and Time Freezing attack over and over again. but, "C D E F G A B C" and "Freeze!" were not unlocked. How can I unlock them? It should meet the conditions.....
