Hi everyone, and welcome to FWsim: Fireworks Display Simulator!

This is a very exciting day for me: FWsim is finally available on Steam Early Access. I released the first version in 2010, and always had one goal in mind: to create the most realistic fireworks simulator available. Something that is close to reality and useful for fireworks professionals, but also intuitive, easy and fun for amateurs and fireworks enthusiasts. It’s been over a decade now, and thousands of simulations - and real fireworks shows planned with FWsim - are a testament that this goal has been achieved.

Fireworks Design is both a science and an art. Unlike other forms of art, pyrotechnics is available only to a handful of professionals. Not anymore! FWsim makes it possible for anyone to create their own fireworks show and express themselves in this unique medium. My intention with the Early Access Launch is to bring this experience to more people. People like you, who might love fireworks but haven't had any direct experience with them yet.

This is just the beginning of the road, of course – as you can see in the Early Access FAQ. FWsim is already a complete fireworks simulation experience. You won’t find an incomplete or half-done product here: from the get-go, you will have lots of fun designing your fireworks shows, and you’ll be able to share it with your friends on social media, Youtube, etc. We’re working to make it easier to use over the next months, and there are many ideas on the table: better graphics, better UI, new game mechanics…

Your feedback will be essential. The ideas of you and other players like you will help shape the next version of FWsim and guide the whole development process. You can join the community here in the Steam forums and follow our social media channels (Twitter, Facebook and Instagram). We also have an active community forum where very experienced FWsim users hang out. Thanks a lot for being here and for your support; I’m looking forward to meeting you in the community and seeing your first fireworks displays!
