The controls and shooting difficulty are intentional. Since players don't move, aiming needs to require actual skill and precision rather than becoming a point->click experience.
This is an early multiplayer prototype that already represents about two months of development. I have a lot more features planned, but I wanted to gather player feedback before investing more time into expanding the game.
Also, the game is completely free. Constructive feedback is appreciated, but expecting a fully polished experience at this stage is unrealistic.
