I’ve tried a lot of particle manipulator/visualizer apps and after trying one for the first time usually determines whether or not I open it again. This ones an exception. The eye appeal is there, it’s up with the best as far as beauty goes...you can see a lot of work went into it. But with limited interactivity options, it loses any and all replay value. It reminds me of games like “Flower”, but doesn’t offer its interactivity. All the potential is there, it just doesn’t offer many ways to play. Really close to being really cool.
