How it works: you see the infinitive of a regular verb (without "to") and you type its simple past form in full. There are 5 levels with 10 verbs each, and you have 5 lives for the whole game. A wrong answer, or running out of time, costs one life. Level 1 has no time limit; level 2 gives you 15 seconds, level 3 gives you 12, level 4 gives you 10 and level 5 gives you 8. Lose all 5 lives and the game ends.
