How to get past level Level 14 1/2

[Snakespeare]

I bought some platinum and leveled myself up to Level 14 1/2 (stuck at 200/328) and I can't seem to level up to 15, I am not getting XP for my playing. I thought the game I purchased would get me to 15. Anyway, I bought another game in hopes of gaining some XP while I play to level up - but no one is playing a game, and if they are, they are private.

So, my question is: Which game should I purchase now to level up past level 15?

Thank you!

I think I get what you're saying. You are level 14+ and you drank a potion of experience (leveled yourself up, you said) and found that you could not get any XP from a kill in Dark Forest.

If I understand it rightly, after 5 minutes the potion will wear off. Then you can get XP until you reach 18th.

I suggest buying the campaigns in bundles. That way you can move right along if your level gets too high for XP.
