You know, the player starts with the first level, you punch him directly in the face. A capital letter? really? As far as i know, this alphabet doesn't differ between capital and normal letters at all. Therefor, and since it's the first puzzle, all combinations should be accepted. BIND, bind, BiNd, bInD, ...
The second puzzle? I tried different things and than thought about how many combinations of the same idea i would have to try and quit.
EDIT:
One thing that i didn't mentioned before: the screen doesn't fit. The game seems too big for the frame. Therefore just the half of the submit-button is visible.
You've added a hint screen at the beginning? Don't make it a separate button. Just add it after the player pressed play. Normally people will just try to play your game and only go back to the instructions, if it doesn't work. But at this point, they are already pissed on.
So, i managed to pass level 2 - really nice one by the way. But one has to have the right idea for this. Next level is ... well the link. But i managed to get the Hint and with the hint from the other guy ... i didn't got to any solution. The 3 puzzles so far are almost like one of these very hard geocaches. I will keep an eye on this game, but can't finish it right now.
