Quoting Nintendo Life's interview with Curve Studios:
"The game’s physics system was built organically over the course of the game. We started by creating the water physics and then layered the other elements over the top, for example, adding objects that the water could carry and making them interact with the world. As the game developed we added motors, joints, and the other elements, each time ensuring that they worked with what we had. This meant that the gameplay never outpaced the technology, instead growing together and supporting each other.
Working with water as a main character was incredibly hard, however. In most video games, players control a single character that can only be in one place at once. The typical things that you use to control a game’s level design – such as triggers, switches, enemy AI – normally rely on a single player position. This was thrown out of the window for Fluidity, since the player could be in hundreds of places at once. We had to devise a system that catered for this in all circumstances, which took a lot of time to get right."
Alex S. from Link-Cable writes: "This past week, Nintendo announced that after more of a decade they would be shutting down the Wii Shop Channel. Many gamers (myself included) have found memories of taking our Wii consoles online, putting in our Wii Point Card numbers and downloading a whole bunch of classic Nintendo, Sega and NEC titles onto the Wii system. But the Wii Shop Channel was also home to a whole catalogue of new games that made up the system’s WiiWare service. It was here that many of the system’s smaller and more experimental titles came into being and many of the developers that brought us these games are now responsible for big indie series’ thanks to their original success on WiiWare. So as a sort of goodbye to Nintendo’s original download service, we’re counting down the Top 20 Best WiiWare games starting with numbers 20 through 11 today (check back next Friday for 10 -1)."
Joseph at Skewed and Reviewed took a look at the game Fluidity for the Nintendo Wii and liked what he saw. He called the game one of the best bang for the bucks at the E shop.
Mini Fortress writes: "Fluidity came to the WiiWare service on December 6, 2010. It’s a 2D game that puts you in control of water to solve puzzles. Developed by Curve Studios and published by Nintendo, Fluidity was well received by gamers and critics alike. I was intrigued because of the positive reaction and decided to download the demo. After spending some time with the demo, I wasn’t impressed and didn’t understand why the game was receiving such high praise. When it became available as a Club Nintendo reward I jumped at the opportunity to try the game again, and I’m glad I did."
