We're still in a great financial position with Universe Sandbox and continue to reinvest our money back into the project. We recently parted ways with a developer, but as with all jobs and all projects, sometimes people simply part ways with a project because they're not a good fit for it or because they're moving onto other things. To be clear, this is not a reason for any delay, and it's not any indication of the status of our development or sales. More recently, we hired another developer to work on sound. We may hire others in the future, too, but it's not always the case that the more people you throw at a problem the faster things get done.
We agree mods would be great, and it's something we want to explore more in the future. But there may be some conception of mods out there that are a bit incorrect. We can't simply flip a switch to enable mods, and what mods look like varies for different projects. We're working with a lot of complex systems, and it would be a huge undertaking to implement it, and likely a big undertaking for anyone working on mods.
