Great idea. It would be cool if it would be a lot of forms to create.

Took me a while to get controls

I love the idea, but sadly either the execution or the controls are poor. I'm not exactly sure which. I clumsily move around trying to rub particles together and sometimes something happens and sometimes they don't. I have no clue.

The idea is great, but the game that resulted may need to be re-designed from the ground up to be actually fun to play. Controls need to be tight and results from experimentation should be immediate and apparent.

I liked the particle collisions, but didn't really get the game. Needs further development.

The idea is interesting, but it is really confusing, and I have no idea of what is happening. Some particles get together, some don't, some get big and purple, whaaat? I'd love to see some instructions.
