User prompt
each tower should display the towerbutton asset, yet now I can't see that on any tower. ensure the towerbutton position remains on the same position as the current position of the buybtn assets set in the code now
User prompt
each tower should display the towerbutton asset, yet now I can't see that on any tower
User prompt
after upgrading a tower, the cost text increases and the available coins decreases, which means the displayed cost text on the button is higher than the available coins, which means it should be transaprent. yet that transparency is not instantly applied, but the game waits for an enemy to be destroyed before making that check to show the cost transparency. ensure that chck is done before killing an enemy, as the available ciins is the correct value that has to be checked
User prompt
Ensure that the upgrade cost text visibility is updated in the `updateTowerButtons` method, which should be called whenever there is a change in the player's coin count. This method should check if the player has enough coins to afford the upgrade and update the alpha value of the upgrade cost text accordingly.
User prompt
you should update the `towerCostText.alpha` in the `updateCoins` function of the `Game` class, where you're iterating over each tower and updating the visibility of the `BuyBtn`. In the same loop, set the `towerCostText.alpha` to 1 or 0.5 based on whether the `BuyBtn` is visible or not.
User prompt
In the `else` block of the same `if` statement, where you currently have a `console.log` statement, you should set the `towerCostText.alpha` to 0.5 to indicate that the player cannot afford the upgrade.
User prompt
Inside the `upgrade` function of the `Tower` class, after the `if` statement that checks if the player has enough coins to upgrade (`if (this.gameInstance.coins >= this.upgradeCost)`), you should set the `towerCostText.alpha` to 1 to indicate that the player can afford the upgrade.

User prompt
ensure that the upgrade cost text follows the same visibility rules and checks as the `BuyBtn`, you need to update the alpha value of the `towerCostText` in the same places where the visibility of the `BuyBtn` is updated. In the `Tower` class, where the `upgrade` function is defined, you already have a check for the player's coins against the upgrade cost. You're updating the `BuyBtn` visibility based on this check. You should apply the same logic to the `towerCostText` alpha property.
User prompt
ensure the upgrade cost text follows the same visibility rules and logic as the buybtn. make the cost visible when enough coins are available, and transparent when not. ensure they use the same check as the buybtn does
User prompt
Since the game starts with 0 coins, the initial visibility of the `BuyBtn` should be set to false. This can be done in the initialization code for the towers where the `BuyBtn` is created.
User prompt
Ensure that this check is performed not only when coins are collected but also when they are spent, so the visibility of the `BuyBtn` is always accurate.
User prompt
If the player does not have enough coins, the `BuyBtn` should be set to invisible (`tower.BuyBtn.visible = false`).
User prompt
If the player has enough coins (`self.coins >= tower.upgradeCost`), the `BuyBtn` should be set to visible (`tower.BuyBtn.visible = true`).

Create a pixel rendition of a winter skyline for a pixel game. The image should feature a light blue sky dominating the scene, with subtle pixelated outlines of mountain crests at the bottom. The sky needs to be clear and bright, showcasing the crispness of a winter day in a pixel art style. Use a gradient of light blue near the pixelated mountain silhouettes, gradually transitioning to a deeper blue towards the top of the image, all in a charming, pixelated format to evoke a serene, wintry atmosphere.. 8 bit.
