I don’t see what’s weird about it, if they are aware of it and possibly have other things that take priority what else could they say? They were just truthful and straight to the point. It’s extremely hard to handle all feedback and stuff from a community as solo/indie devs, it’s not easy on any level for that matter. If you took several seconds more and emotional effort to be super nice to every single person who interacts with your game we wouldn’t have any games releasing at all. It’s important to keep your responses to a minimum while also making it clear what the situation is. I think that was a good reply, not offensive at all and made you understand that they know and will fix it.
