Ken's Snake Game

[SierraKen]

This is a small game, but it can be fun. :) Move around the snake on the screen with your mouse and avoid the red bombs while eating the yellow food to gain points. Once your health goes away the game ends. After a short amount of time the bombs and the food re-locate.
This is my first game using a snake tail I invented tonight. I know I could have used that one fading tail effect, but I wanted to try something different just to see if it could be done. If you look at the code, you might notice that I use CLS after 2500 plots in order to reset the variables of the snake. I tried it other ways without having to use CLS but couldn't do it for some reason. But that's OK, the player doesn't notice it anyway. Anyways, please tell me what you think. I hope you enjoy it.

Hi Ken
fine to meet another your program

I find it fine, the gameplay is good... I have seen that it is not necessary to get all the foodpoints on the screen to pass the next level.
I have taken some red bombs....
fine sound.
here a screenshot of my playing

 

Good job! And Thanks to share.

[SierraKen]

Thanks TempodiBasic! Yeah the levels just change when your snake goes a certain distance. This game so far is just an example game to make a snake pretty much. I might enhance it soon. :)

[SierraKen]

I added enemies that chase you. :) Any comments are welcome as usual.

Fun game.
Why is there no possibility of regaining lives ?

[SierraKen]

Thanks for the suggestion Euklides! I added the ability to get more health every 100 food pellets you get. I also made the game harder by speeding up the enemies every time the screen changes. It gets pretty hair raising after awhile. :)
Here is the update:

Code: QB64: [Select]

1. 'Use your mouse to guide the snake around the screen to eat the yellow food pellets.
2. 'Watch out for the red bombs or your health will go down.
3. 'Also watch out for the enemies that move toward you. They will also make your health decrease.
4. 'The game speeds up a little more when the screen changes.
5. 'Your health increases by 50 points every 100 food pellets.
