Fantastic typing game, I got to the point where my upgrades outscaled any difficult though so I had to just stop before actually losing.
It's not the most creative game but it is a lot of fun and is well made. The only complaint I have is that later on when the boss shows up it the first jumble of letters you have to type can include lowercase l, uppercase L, lowercase i, uppercase I and they all look so similar if not identical you basically have to just guess until one of them works.
