Very difficult and rewarding. A bit too much Portal, but it's a great game still, so no knocking it for that. I love the level skip. I've used it once so far, and then I went back after I learned something on a further level. For a game that presents different challenges each level, a level skip is very nice. I don't have sound on my computer, but I don't see anyone complaining, so I am envious of them. Graphics are great and simple looking. The only complaint I have is that sometimes things don't work perfectly. Little bugs that haven't done anything awful yet, but something to look into.
I have a question. Why should I play anything but thief? The runes for all the other classes are amazing on the thief, and only moderate on others. Is the paladin supposed to even be played? I do not like that mask. Barbarian & Thief are all I grab.
Difficult controls, occasional legs sticking together, and low levels are great weaknesses that could easily be fixed. Love the concept, and aesthetic properties are perfect for the type of game. 3/5
