The movement keys are redefinable, which I like. I don't like wasting time finding out how to do things in a game.
You, the bear, have to eat apples to survive hibernation. Neither the screen nor the inlay card tell you how you eat the apples. The answer is to press the 'up' key, whereupon you lift your head to catch the apples in your mouth.
Fat lost during exercise, or put on by eating apples, is registered. Squirrels drop acorns which can knock you down.
After a fixed period you have to walk across a ski slope among skiers. On entering the cave you have to pass spiders to reach the den. When you enter the den you walk to your bed and sleep, and the passing winter months are recorded on a calendar.
In spring you return to the orchard. During one game I made three journeys with no change of scenery, and there was no hall of fame at the end. Graphics are no better than I expect nowadays, and nothing in the game makes it stand out.
