A long time ago in a galaxy far far away ...

I like The Powder Toy. This is a great game with a great community. In this game, a huge set of tools allows you to create all sorts of things. Some people create a monstrous electric circuits, and even full games on their basis. Other players create a variety of explosive things. Some people more like to draw and design beautiful things. And some are trying to construct a new "glider" with elements "Game Of Life". The rest just like to mix one with the other elements in different proportions and watch what happens.

Once upon a time there was a game like Burning sand 2. This game was also a “sandbox” (but simpler than TPT). And a lot of modifications have been made for this game. One such modification is called OMNI, and was a simulation of the universe (or rather simulator space wars). Creates several planets, activate simulation and see how they start to fight among themselves, annihilating each other. An exciting spectacle. Here is a video not to be unfounded: https://youtu.be/DCXbQKRgMZI

So. Will be in the game The Powder Toy something like that? I looked through a lot of mods for TPT but could not find anything similar. Mostly mods focused on the expansion of available ingredients and their interactions. (If you still have this mod, I will be very grateful if you share this link)

Additionally:

In OMNI you can see the source code (exe file can be opened with any archiver). Program code is written using a special syntax (BS2), the documentation which can be found only through archive.org( http://web.archive.org/web/20110707043535/http://www.fallingsandgame.com/wiki/index.php/BS2_CodingHelp_BS1_MODDING ) . But the source code have is more than 85,000 lines.
