I enjoy the concept of this game. Its fun to search rooms and build collections, the holiday themes are fun. However, the life cost to enter each room is too high, needed items are very expensive in game currency and the rewards for leveling up is not very generous. I purchased a few coin packs (with real money) thinking I could make better progress, but they dont last long as store items are expensive. Also, expensive items dont last very long. Ive noticed that a lot of people on my friend list have given up (cobwebs). I think you would retain players if success was not so hard to achieve.
Update: not sure whats happening the last few days but here seem to be A LOT of glitches. Game has frozen after completion of room without gaining rewards. Expensive items (first aid kits and meals) have vanished from my inventory without being used. Certain gifts can no longer be given but appear as options (lenses) Please fix this.
