Finally, I finished a new version! I think we can call it pre-alpha. 

What's new:
- way to attack: now you shot the enemies with different types of ammo
- characters: two selectable girls and one demon girl to play
- reward system: visual novel like slides
- core gameplay: you need to drag & drop green rot to the demon girl to make her freedom and red stuff to heal, upgrade, or boost your character
- more comfortable interface
