PLEASE READ THE INSTRUCTIONS BEFORE PLAYING! I didn't have time to make a tutorial (sorry!)

Rules

• Survive for as long as possible.
• Move with WASD.
• Towers spawn in random places.
• Each tower blocks access to 1 outermost unblocked ring. If there's 1 tower anywhere on the map you can't go to 5th ring, and if there are 4 towers present you can only stay in the middle.
• If you stand on a ring that's about to be blocked by a tower, you'll be pushed back on the closest available ring.
• As the game goes on, towers spawn faster.
• Game ends when the 5th tower spawns.

How to destroy towers

2 ways to destroy towers: shooting and direct contact.

Direct contact

Move on the same square as the tower. Timing wheel will appear above your character. Press Space when orange cursor is in blue area on the wheel. Destroying towers in this way will give you $75. You can't use this method if tower is on a blocked ring.

Shooting

Click "Shoot" button in bottom-left corner using mouse to destroy a random tower. Alternatively, click the tower you want to destroy. Each shot costs $50. This is your only option to destroy a tower on a blocked ring.

How to get money

Click "Build" button in bottom-left corner using mouse to place a factory on current cell. Building cost increases with the amount of factories you have. Every 3 seconds you gain money from each factory. The further from center the factory, the more money it brings. When a ring becomes blocked by a tower, factory's HP starts to decrease. When factory HP reaches 0, it is destroyed.

Strategy

Build as many factories before towers start spawning faster than you can handle. Then rely on Shoot button to destroy the appearing towers. You should have enough income from factories to afford the shots.
