I'll grant that it's a very interesting concept. Having "died" in the middle of the second page, I'll offer a few thoughts--
- Once you've found the words in the letter, or you've clearly missed everything because what's left is just "but" and "was" and "that", it would be nice to be able to fast-forward through everything else fading away.
- While the concept is solid, it's frustrating to be able to "lose" a puzzle game--a game shouldn't be trivial, but also having had the game end on the second page, I'm not feeling excited about having to go through it all again.
- It's kind of a guessing game. A lot of things that looked like they ought to be important words, like people's names, or "angry", weren't. The life system is a good way to keep people from just clicking everything as fast as possible, but it also discourages experimenting (and because there's also a timer, there's an impossible balance between "I don't want to click a wrong word" and "I don't have time to read all the words and think about which ones are important").
I get the mechanic, but I feel like there should be a mechanism other than "losing and running out of life".
