Just a quick heads up, although the listing for the game here only shows it was available on the PC, the game was available for quite a few platforms including the Wii U which is how I played it.

Kind of a weird experience when it comes to these kinds of games. While it’s obvious that the idea behind it was “what if Harold and the Purple Crayon was a game?” the execution holds it back from being better than it is by limiting the creative freedom of the player quite a bit.
Not bad by any means, but you aren’t missing anything by not playing it either.
