Hey, I think it is a cool concept as it helps practice typing as you play. That makes it a bit difficult, which I don't mind, but having to go back to the start each time gets old very quickly. Maybe give 3 lives like classic games or do a checkpoint system so you don't have to go all the way back. The first level is basically a tutorial and no one wants to play the tutorial every single time they mess up. I only got to level 4 and would have liked to go farther but get very tired of playing the first level. Every time you send players back to the title screen you lose a lot of them.
Keep at it though!
