I'm sorry, but how is "click exactly where I point you at, repeatedly" a game? If it had a scrolling list of instructions that scrolled up as you completed each step, it would at least be a tiny bit of a puzzle or game. It can't even claim to be a walkthrough on how to make this cobbler, since it doesn't give measurements.
This has the look and feel of a casual, approachable game, but the fact that you have only a limited number of attempts without having to pay takes it out of that category. It means that anyone who finds themselves having to re-try more than a couple of times will find themselves blocked from finishing the game. I might conceivably pay one time for unlimited tries, if the game was fun enough, but paying to have another limited number? No, thank you.
Nice concept. I wish the letters were actually hidden, not just invisible until they're moused over - that would mean that kids would be looking for the shapes, not just for the grey areas in their magnified area. It would also be nice if you could click on a letter and get a hint on its location - otherwise if you can't find them all it just feels pointless.
