On the final screen after killing all the enemies, a number appears. I don’t remember exactly what it is, but below it, the word 'text' is written. So I thought it was the score. Maybe that number is also displayed by mistake.
OOHH I see, that is a perk selection screen, its not clear since I made it in a rush, but you are supposed to click one to get a perk and move on to the next stage.
