I am at level 4. I was going to quit as it seems the costs were escalating to the point of silly very fast.

However I got 4 day boasts on the spinner which helps.

I noticed that every time you spin the rewards get bigger, looking forward to getting a multiplier, based on what buddy says above, it should happen every 6th spin or so.

Also when you spend diamonds on spins and why spend them on anything else the cost goes up, but it settles back to 25 after you get your next free spin. Also paying for a spin doesn't reset the clock for free spins which is good.

I managed to get a couple of keys from clicking on lower value girls last night. Haven't seen that before or since. Not sure what is going on there.

Some advice, don't use keys unless you can't progress on chat with any girl. The higher the level, the more you get from the boxes. Well every second level it goes up.

The game might get ridiculous but I am in it so far.
