What the developers have to say:

Why Early Access?

“FWsim started as a tool aimed at professionals and fireworks enthusiasts, but over the course of the years, more and more people got hooked to it and its creative possibilities. That made me realize FWsim could grow and evolve to appeal to a wider audience and not just firework experts. Steam Early Access is just the right place for that. It allows us to get feedback in real-time and shape the next iteration of FWsim. We want to make it a powerful, deep and realistic experience, while still being intuitive, easy-to-master and fun.”

Approximately how long will this game be in Early Access?

“The plan is to be in Early Access for roughly one year – until Q4 2020 or maybe Q1 2021. However, that could change - there might be great ideas from the community that take quite a bit longer to implement. And of course, full release will be only another step in a long journey – I expect I’ll continue working on FWsim and release more updates for years, just like I’ve been doing since 2010.”

How is the full version planned to differ from the Early Access version?

FWsim is already usable from top to bottom, and it’s a complete fireworks simulation experience. That being said, I have big plans for the full version: New graphics, better user interface to make it more intuitive, more and better 3D environments… The sky is the limit though – the community’s feedback will be essential to guide my priorities and shape the development of the full version!”

What is the current state of the Early Access version?

“As it is right now, FWsim is ready to use and fully functional. My plan is to build upon what it already has; the first changes will be incremental, and major “revolutions” will come further down the road.”

Will the game be priced differently during and after Early Access?

“The price of FWsim will increase on full release.”

How are you planning on involving the Community in your development process?

“Getting feedback from the Steam community is the most important aspect of the Early Access period. FWsim already has a strong userbase among fireworks enthusiasts and professionals. Now we would like to get feedback from a wider audience of gamers. We will listen to all of your feedback, and features are prioritized according to that. We are especially interested in what we need to improve to make it easy to get started - even without any previous experience in fireworks. So the community’s feedback will be essential not just for fine-tuning, but for guiding the whole development and design process.”
