Riddles for you?

Ever since I saw this link on Eastpaw's blog for puzzles, I've been hooked on it. Let me recommend it. Note: you do need time and lots of effort for this.

What's more irritating was that I counted wrongly on level y and jumped to level a and merry-ly proceeded without noticing. And then, bump, entangled in a mess of my own making.

[Edit: Hopefully didn't leave many clues. Although the first few levels are like 2 minutes a piece.]

Shucks! I can't solve stage x without the correct answers from the previous stages and 45 mins gone past without me realising that my previous answer was the one giving me grief. And that was also why I went for a wild goose chase.

Seriously fun though.

[Edit: time now 0058hrs. Been stuck at level 14 for over an hour. What am I missing here??]

[Edit: 14 Dec, 1749hrs. Completed batch 1, 29 level. Can't believe I was stuck on level 16 for 2 days!]
