Challenging, but not exactly in the best way.
Well, right off, the game is a solid typing game.
I'm a terrible typer, so it's really hard to play for me.
Nothing too special, but I did like the freeze powerup.
As said, terrible typer, so that helped a lot.
The problem is the word difficulty doesn't match the level.
I would be on level 1 or 2 and be typing words I've never seen before and occassionally questioned if they were even words.
Also, and maybe I'm mistaken here, but were some of those proper nouns?
If so, I don't think you should include proper nouns in a game like this.
Maybe you didn't and I was being tossed words on early levels that were so unfamiliar that they seemed like names of specific things and places.
Long story short, decent typing game with nice powerups, but needs an adjusted word difficulty as compared to the level.
