Hey, long time no see, right? :~)
Sorry about that but I got caught up with other matters and didn't really have much time to play games.
So I took another spin at it and it turns out you are correct, it was just that I was clicking on the power-up more than 1 time and that's why my game was ending so quickly.
However, I think the game is very hard from very early on, and that you should make it a little easier for the player to reach a few power-ups early on before speeding up the point losing rate.
Cheers, Stavros.
