I finally found them
Scoured every inch of the map that I could stand on and still came up 2 short,...so I figured there was somewhere I hadn't been. Then it just suddenly hit me, Take a leap of faith
First leap lead to death cos I rolled off and kept rolling onto the thin ice, but I got the last 2 none the less. Wish I'd thought of it sooner.
As it was I stayed up untill 2am hunting for them......good thing I didn't have to get up for work this morning.
And for the record, I'm not bitter....I like a challenge, it's no fun when it's too easy. For a small game, it was very nicely done although I can offer one small piece of constructive critisism: (hopefully without giving away a spoiler)
Had I not already been familiar with the map, I doubt I'd have been able to figure out where to use the de-icer. Only reason I got the idea to use it where I did was because I knew from fantasy world that there was water there. Just my 2 cents worth.
