Also fixed some bugs:
- In 2 players mode, the game can't pause if player 1 is dead.
- Now player 2 can call pause menu.(It's a big freaking bug in UE4, I was banging my head against the wall for some time :0)
- Another UE4 bug that if 1P pauses the game and resume, 2P will stop receiving inputs from controller.
- fast mode bug.
- other minor bugs that I can't remember now got fixed.

The stage 1-2 is working in progress now, will be released soon, and there might be a minor rise in the price.

One more thing, I've shut down the Indiegogo page.
I did not host any crowdfunding page. And if I'm gonna, I'll also post an announcement here.
So if there are any crowdfunding pages about my game, they must be scams,.
