Instructions are confusing and ambiguous.

Well, that may be my lack of intellect or something like that, but I can't even pass the first "level" of the game because the problem 'instructions' are confusing and can lead to ambiguous conclusions, which further lead to more confusion once you get to the "IDE" part where you have to solve the code later, since the commented bits of the code tells nothing about it. Without much to do about it, I ended giving up on the "game" before even solving the first problem. Considering other programming games I checked, this seems to be a recurring problem. some claim to help you learn something, but they require prior knowledge of the very thing you're trying to learn or they don't feed the correct amount of information.
