Retoohs post-jam update v2.0

During the voting period of the GMTK game jam, everyone pointed out some small issues, so in this update I fixed most of them

What's new

• Added diagonal movement
• Improved the top bars UI
• Buffed the zombie mode, now the zombies can pickup drops
• Added an in-game tutorial
• Now you need 1500 score to get to the boss instead of 2000
• Mobile version available
• Added volume-control sliders
• Reduced the role switching time
• Fixed minor bugs

I hope that now many of the issues mentioned in the comments, are now fixed :)
