Thanks for the feedback! You're not the first one struggling with this ;) Some more playtests and we would have come up with clearer communication. But there was simply no time left :D
In "Type" you have to type the word "countdown" (letters at the bottom of the screen).
In "Press" you just use the numbers on your keyboard. Pressing 9 counts down to 8 then you have to press 8 and so on :)
