Thanks for your reply.
We are currently working on updating the game, and it has been slowed down since this release, we have also fixed the bug where the orb gets stuck when exiting a host.
The orb is now easier to control, it doesn't fly off in the distance anymore. It is also now easier to possess an enemy, and the orb will now survive for a lot longer without a host.
We will also add in a screen to properly describe what's going on and what the player needs to do in the game.
We hope you will enjoy the final version when it is released.
Thanks again for playing.
