Good news. After replaying my old demo of the game a few weeks ago, I realized that the controls were absolutely horrid. Everything has been changed and fixed, and the controls are nice and responsive now.
On another note, Epicopter is going to be back with another demo in the near future... And I've turned it into a fully procedurally generated post/present apocalyptic strategy/rpg hybrid. As It stands right now, it's really fun to play, and i'm currently sorting out the details of the story. I've added tons of new content, and I have really high hopes for the future of this game... I'm even starting to consider selling it for 5$ or so...
