Weapon Evolution: Craft Run

Description
Weapon Evolution: Craft Run is a third-person 3D arcade-style shooter where the player moves forward and shoots automatically at targets with their main character: A floating, static hand wielding a weapon. The only action the player is required to perform during gameplay is move left or right.
As the player goes, different targets will appear in their path, including enemies that will shoot back at them, ammo cylinders that can be filled with projectiles, and signs that grant the player buffs or penalties. For each obstacle the player finds, they must decide whether they are worth shooting and then whether they are worth passing through, as that is the only way to obtain buffs like improving your weapon's range, fire rate, or technological level (advancing through the ages).
Near the end of the level, the player will encounter a large amount of obstacles filled with cash, where their only option is to shoot them down to get through, else they stumble on them. For each layer of obstacles, the amount of cash gets larger and larger as the player approaches the end.
After losing/finishing the level, the player can use their cash to buy better weaponry to make future runs easier.
