A tower defense game that can design routes freely.

You can rely on your intelligence to design defense lines to resist the attacks of various monsters, so as to protect your shelter.

---How To Win ---
At the beginning of each level, some enemies will attack the shelter from the left.
When the sanctuary receives certain damage, the game will fail.
Use your facilities to destroy enemies. When the level is over, if the shelter is not captured, the game will succeed.

---Battle Prepare---
Before the battle, you can choose the facilities used in this level.
The selected facilities are displayed in the right interface and can be used in this level. Otherwise, they cannot be used.
The available settings are 8 by default, and more fields can be unlocked as the game progresses

---Battlefield Operations---
Click the facility on the right to select it, and then build it in the blank area of the battlefield.
Blocked parcels are marked in red.
If there are not enough resources, they cannot be built. The number of resources is displayed in the upper right corner.

---Battlefield Resources---
Each battlefield facility will consume a certain amount of battlefield resources.
Battlefield resources need to manually click the resource package on the battlefield to pick up.
The specific number of resources is displayed in the upper right corner, and each level will be reset.

---Monsters---
Generally speaking, the enemy will directly look for an unstopped route to attack the shelter.
The enemy will attack the defense facilities along the way (if the facilities are not on the enemy's route, they will not be attacked)
However, some special enemies will have different abilities and different behavior patterns.

---Units---
Most of the defense units are very vulnerable and easily destroyed by the enemy, but there are also very strong facilities.
Whether the defense unit can attack the enemy, block or be attacked depends on the facilities.
Once a defensive unit is placed, it cannot be removed by the player.
