A typing game about forms

Paperwork

A stack of forms. A stack of done forms. You in between.

1. Each blank shows a letter. Press that key to fill it in.
2. The faster you are, the more it pays.
3. Each right key in a row builds your combo. A wrong key ends it and costs you points.
4. Sign every form with the letter shown, then hit the space bar to stamp it.
5. Urgent forms pay double, but you get half the time.
