It's an extremely difficult game for those who don't have the skill to type fast (me). It would be interesting if the game started with a lower difficulty, perhaps with a longer timer or a simpler word selection, if possible.
I also didn't feel much of a difference in the multipliers, perhaps a higher limit would be better.
Despite failing miserably at trying to get past the first level, I had a lot of fun with this game, the art and music are also very cool.
