v0.6.0

I'm still working on polishing the entire game flow, some things could be still unbalanced and buggy, so please let me know if you face any problem. Thanks a lot to the people that write me and keep me motivated, I hope I could give back to you the joy and excitement you deserve, with this and the future updates of the game.

This is the list of updates and fixes on this version:

• Nerfed Overclockers just a bit. They will no longer be chain-able, just to avoid that kind of exploit. (Do you think it should be allowed?) 
• Replaced the BOMB with a BOX, to make it more clear that each time a game finishes a BOX is left to the next players that play in this async multiplayer approach.
• Added a simple menu to pick what item to leave in a box.
  • I thought about adding the chance to write a small message too, but maybe we can integrate a simple login so we just use the user name or something so we avoid custom text inputs.
• Added end game screen structure. It has the high scores and a quick share button too. It is getting prepared to expose a bit more of the data gathered during play.
