Please modify the game with the following visual and gameplay improvements: 1. Change the camera perspective: - The game is 2D, but use an isometric or angled diagonal top-down view to create a 3D-like visual effect. - This will give the game a more dynamic and immersive appearance compared to a flat top-down view. 2. Tower placement zones: - After placing a tower on a build zone, remove or hide the build zone indicator at that location. - Only the placed tower should be visible at that spot, so the player clearly sees their defenses without clutter. 3. Coin/Gold display: - The collected gold or coins should not be hidden or invisible. - Move the gold/coin display UI element to a prominent, central position on the screen where the player can easily track their resources. 4. Tower upgrades: - Allow the player to upgrade towers by clicking directly on the tower itself. - When a tower is selected, display an "Upgrade" button or text above it, showing the upgrade cost. - For example, clicking on an Archer tower shows "Upgrade: 50 gold" above it. - When the player spends the required gold, the tower upgrades to the next level (e.g., Archer tower upgrades to Crossbowman). These changes will improve gameplay clarity, UI usability, and overall player experience.

The current map is too plain and simple. Please redesign the battlefield to include more visual complexity and tactical depth. 1. Add multiple enemy paths: - In early waves, enemies can come from one or two directions. - In later waves (e.g., wave 6 and beyond), introduce additional enemy paths from different sides of the circular map to increase challenge and strategic placement. - Paths should be clearly visible and vary slightly in curvature or direction. 2. Show tower placement zones clearly: - Add marked or highlighted build areas around the enemy paths, where towers can be placed. - These areas should be visually distinct (e.g., with outlines, grids, or glowing borders). - Ensure the player understands where towers are allowed and where they cannot be placed. 3. Make the map look more immersive: - Add some visual elements like terrain features (rocks, trees, ruined structures, etc.) that do not interfere with gameplay but make the map feel more alive. - You can add background details like fog, mountains, or water to give the environment personality. The goal is to make the battlefield look more interesting, give the player clear build locations, and progressively introduce multiple enemy paths for a better gameplay experience.

It is basically correct but how do I determine features such as castle shapes, tower variety, enemy numbers, health etc.
