Make your own rules and let particles behave and interact however you want.

I recommend downloading the game for better performance.

You can delete pixels with the right mouse button.

How do you create particles for the achievements? Ive got some but I cant create a working fire particle or a virus either. A tutorial for these would be nice, or maybe a hint too!

Hi! If you're having trouble with the virus, there's a solution in the screenshots. 

A few hints for the fire: the fire works just like the virus, but uses the tag of the wood under 'move if'.  So if your wood got the tag burnable or something, select it on your fire. 

And if you also need hints for the smoke: It is upside down sand and randomizes directions. 

If I have time I'll maybe create a guide for these. 

Thank you!

This was cool but not being able to edit existing particles was a bummer.


Really cool simulator! I like how you can make your custom tiles with their own properties, its fun to watch the physics on them.


Nice game and very satisfying, I feel as though the ui could have more polish. Great job!


This game is so neat! It's always a good sign when it's just fun to watch particles animate in a game sdhfsd

Some of the instructions are a little unclear (i'm not entirely sure how tags work?) but its super fun to play around with! 


This is really cool! The physics are fun and reminds me of The Sandbox games. It might be cool to also be able to drop living pixel characters to see how they would react to the environment and chaos lol
