Thanks for the feedback!
I actually considered adding a time mechanic, but that makes the game too dependent on luck, and I really want the leaderboard to be based on skill, not chance.
For example, what happens if you only have a few seconds left and, due to bad RNG, the exact letter you need just doesn't spawn? The player ends up losing simply because luck wasn't on their side.
By dropping the timer and using a health point system instead, I can guarantee that if a player loses, it's due to a mistake or lack of skill, rather than just bad luck
The game is made in such a way that letters needed will appear almost always but still there is a chance to have bad luck and wait a couple more of seconds waiting for the right letter just for bad luck
