I can compile the wallet tomorrow, i tried it just now, got the daemon running. The QT's gamepage needs the qt webkit module which i don't have but will install tomorrow. after that it's a walk in the park.
It's my understanding the game was to be removed from the wallet...
The FlappyCoin game inside the wallet was too heavy. we decided to skip it and update straight to the built-in exchange inside wallet (which is completed). Will release the new version tomorrow.
If the game is still there... it should be removed as it links to the old dev's server (and who knows how long that will remain up)... So you don't have to let that stupid idea of linking to an online game inside the wallet hold you back from compiling. It adds nothing innovative to the wallet.
Let's keep the wallet design as simple as possible so it's more likely we can get it compiled. The old dev messed up the wallet more than improve it.
