I might be screwed.. I might have started on an odd number from before. If I do very well and finish I might not be able to get the last achievement :( It will read at 99. Right now it reads at 79 in achievements even thought item hunt says 80xP Do I have any options?

Item Hunt tends to say something along the lines of 'Are you ready to start level X', which is one level higher than the amount of levels you've completed (which is what the achievement counts). You should be fine.

haha, I see, thanks :)
