The game has a beautiful snowfall in biathlon on a real Lynx. This was the first thing I noticed when I saw it in May last year.
The graphics is designed for a real Lynx. I have only played it on a Lynx - never seen it on Handy.
It is very important to have sound on when playing the game. The contrast of the timing indicators depend on from which angle you look at the Lynx screen. But if you rely on the rhythm of the sound you have no problem to keep the character going.
I am still waiting for my copy of the real thing. The version I have played was a beta release that was far more polished than most of the final releases I have seen.
I have not played through the whole campain yet. I usually get hooked on one subgame and play it over and over again. Biathlon and slalom are my favorites so far. Mainly because of the enjoyable graphics and good controls.
