Unsigned int64 ago, people use stones to deal ranged attack.

But a good stone-thrower requires a lot of training, so they invented the slingshot to fire stones. This new technology helped the fight with other creatures greatly.

But one day, the earth is invaded by unknown creatures. All of your kind has mutated and you are the only one survived! And they along with a lot of zerglings and titans destroyed your homeland!

Now it's your time! Show me what you can do with this ultimate weapon as an ancient ranger!

Controls:
WASD : Move
Left mouse button : Charge and fire
Right mouse button : Emit the Force (It requires cooling down after using it once, and you will hear notification sound effect when it's ready)
Left Shift : Sprint
Q : Switch weapon

Instructions in battle

There're two kinds of weapons.

Stones are reliable for dealing a lot of DMG, but requires charging for a while. Besides, stones have strong knock-back on light enemies.
Arrows now have higher fire rate and DPM but lower DMG. You will have to choose proper weapon to deal with different situations.

There're three types of enemies.

Orcs are normal one. You will have to kill it by at least two stone shot or multiple arrows.
Zerglings now have higher speed and hp. You won't be able to kill it with only one arrow, but one half-charged stone is enough to take it down. Think carefully about weapons.
Titans now will not be useless! Approaching titans will slow down your speed and if you didn't managed to escape you will be surrounded by zerglings suddenly!
Good luck!

BTW: Please run at full screen mode. There may be some bug in window mode due to some reason from Unity.

Some Questions:

Q: Why there is no dot in the center of screen to help aiming?

A: Because you are ancient ranger! Do you think you'are able to fire the stones precisely? No. Try to guess the trace of your weapons and make them of good use. Good luck!

Q: It's hard to aim and shoot when lots of enemies are moving towards you?

A: Yes. If there's an enemy blocking your slingshot, the dmg of your weapon will be really low. So keep distance from them. In fact, once you are surrounded while your Force isn't ready, you will die in seconds.

Q: Why does the movement speed is so low?

A: Because trying not to get surrounded is part of the game. It will be too easy if you can move at high speed. Use sprint and force to avoid being surrounded.

About movement speed:

Thanks to everyone who made suggestion!
I tried to improve movement speed, but the game is just getting too boring. Currently zerglings could catch you when you are not sprinting away from them, and orcs could catch you when you trying to simply hit & run. If player has higher speed, orcs may be harmless even with increased amount. To avoid this, both player and enemies' speed must be improved. In that case, zerglings would move too fast.
So in my opinion it's hard to improve movement speed while keeping it interesting. It would be different if I added more mechanics, enemies and skills in it.
I've uploaded a alternative version with higher speed.
Orginal Version:
Forward Speed : 6 Strafe and Backward Speed : 3 Sprinting Multiplier : 1.5 Hp : 100
Higher Speed Version:
Forward Speed : 7 Strafe and Backward Speed : 5 Sprinting Multiplier : 1.8 Hp : 200
