I think the issue at hand is encouragement/discouragement. As it stands, the game punishes you too harshly for losing. We feel discouraged from playing because we risk losing all our progress and much more. However you want to fix the problem, it should be thought of as a matter of encouraging players to play more even when they lose. I would suggest:
1. Give players a small credit reward for losing.
2. Keep the half-fuel can, that's already a good feature.
3. Have the player lose no medals, or lose only half the number of medals that you'd gain for winning. That would go a long way towards softening the loss.
4. Finally - and this is not my idea, it's been suggested by others, and it's a really good one - offer cards as an additional reward for winning. Say, two or three commons for a win, with small chance of rare, and only one common for losing.
It just hurts and it's no fun to log in day after day and just slide down and down levels. As the players, we know what we want. Thanks for listening.
