Meta Galactic Llama Battle at the Edge of Time. Here's a video of it on the Commodore 64. I can't remember if I had it for the C64 as well, but definitely played it on the VIC-20
As with most of Jeff Minters games it kind of takes a slightly different approach.
You're a Llama at the bottom of the screen and you can move left and right. You can exit one side of the screen and come in the other side as well.
You shoot lasers out of your mouth at 45 degrees and you have to shoot the spiders falling from the top of the screen.
If a spider reaches the ground it starts to crawl towards you making evasive action essential.
All very interesting so far. To add to the complexity and the control you can also raise and lower a ceiling for your laser to bounce off of to assist in shooting the spiders.
After some fumbling I put created a little game inspired by the Llamas.
Below is the game and here is a Link to project on Scratch website if you want a peek inside. https://scratch.mit.edu/projects/61239650/
It's been fun developing a game in Scratch. I'm most definitely not an expert and I expect there are a lot of refinements that could be done to the code to improve the game but it plays similar to the original. I hope you enjoy it.
