You finished the tutorial and learned how to survive.
You managed Stage 10. Hopefully you are warmed up. That was just the beginning.
Congrats. It seems that Stage 20 was not enough for you.
Learned well you have, young Xterminator. Stage 30 is yours.
You mastered Stage 40. Even your shadow is afraid of you!
The odds stood against you. Only a true Xterminator can dominate Stage 50.
