Hi,

as most of you who read this I loved this page.
I was interested again in automate the puzzles on this site which i didnt tackle yet.
But since most of them are visually broken I kinda lost interest on most of them.

Do you know of any other site which has a similar feature as to automate games like Mortal Coil and so on?

There are a few sites going in that direction, but no 100% matches as far as I know.
All of the sites below take you code and run it on their servers, with a varying amount of languages to choose from.

codingame.com
There are puzzles (with a correct answer to find, some with visual animations), a bit of code golfing, optimization problems and also multiplayer games where your code fights against other programs.
They host a contest soon.
The website even allows users to upload their own games and puzzles. The only one that expects you to solve levels offline like you know it from here is Number Shifting, clearly inspired by pusher boy.

They host regular algorithmic contests but also optimization problems once a month (with a duration of 6 hours or 6 days, switching between those two). Here's the last one.

topcoder.com
More optimization contests. Some with a fun topic, others with a real-world use case and money prizes. They host finals once a year - onsite if possible.
In particular =true&types[]=CH&types[]=F2F]this list of current events - as the website is hard to navigate. Use clist.by to find upcoming contests. Click here to get an idea of a previous contest. The animation is a "minimal case", maps can be up to 30x30 with 10 and more farmers to control simultaneously.

Preview is crashing the server, I hope that the formatting isn't broken.
