User prompt
add longer enemys. They will come after get 100 score. Every 100 score pass enemies come longer and longer
User prompt
snake can be move only mouse button is holding.
User prompt
when snake reach the last mouse position dont change the face rotation
User prompt
when snake is not moving its head are shaking fix this
User prompt
Scale ratio isint working properly Fix this. It must be like triangle lookalike
User prompt
When player eating First segments are going to be bigger. For example if head scale is end tail scale is 0.2 and middle segments must be ratio scale in these two numbers. (The numbers is example use active scalse)
User prompt
Make a player snake tail more smaller than head. The segment scales are rated whit its positions
User prompt
add rotation to enemy head and segments like a players.
User prompt
Oh c onn. Use snake head asset for snake head. Use snake body asset for snake body. Fix immediately.
User prompt
I change the snake parts whit square. So you need to fix like its need to rotate when following the mouse.
User prompt
Add mega fart to player. This is like a nuke particle. It will be shown when player eat something
User prompt
- Player can fart every eating lure
User prompt
- Fart is not working properly. Fix this - Remove win condition
User prompt
-Add a fart to player. It trigger when player kill the enemy. - Increase enemy speed - Δ±NCREASE ENEMY SPAWN RATE -
User prompt
Remove enemy fart mechanic
User prompt
Please fix the bug: 'TypeError: Cannot read properties of undefined (reading 'x')' in or related to this line: 'var dx = playerPos.x - self.head.x + (Math.random() - 0.5) * 200;' Line Number: 79

Snake Minigun Mayhem
Initial prompt
Make me a classic snake game. But add a minigun to this snake. It will be shoot when enemy is nearby. Every time shoot the enemy snake going to fart as flame.
