Really love the concept. And agree that words, or a look-ahead, would make this more enjoyable. Right now, it is pretty hard.
Many, many times I pressed the wrong key. Simply because the pixel font made it hard to distinguish some of them: C/G O/Q
And then for some reason I lost 2 hearts. Because the following letter immediately registered.
Any encouragement, like 5-in-a-row, would also be appreciated.
PS: Love the art.
