    Feline Fortress Hotfix – Nextfest Demo (v1.1.0.2)

    Hey there, Feline Fortress community! We hope you’re enjoying the early Nextfest demo of Feline Fortress. We’re incredibly grateful for the fantastic feedback and support you’ve shown us. As a small indie team, your input is invaluable in helping us polish the game. We’ve just rolled out a hotfix to address a few key issues and make your experience even better. Here’s what’s new: Removed Redundant Files Issue: Our initial build contained some redundant files, leading to a larger installation size. Fix: We’ve meticulously combed through the build and removed these unnecessary files, significantly reducing the overall size. Compressed Over-sized Textures Issue: Some textures were larger than necessary, contributing to the hefty download. Fix: We’ve compressed these textures without compromising on quality, helping to streamline the game. Installation Size Reduction Result: Thanks to these optimizations, the installation size has been reduced from approximately 1.25GB to just around 280MB. That’s less than a quarter of the original size! Fixed Inverted Gameplay Controls Bug Issue: Some players experienced inverted gameplay controls when opening and then closing the game menu. Fix: We’ve squashed this pesky bug, ensuring that your controls remain consistent and responsive throughout your gameplay. Looking Ahead We’re continually working on improving Feline Fortress and can’t wait to bring you more updates and features. Your feedback drives our development, so please keep it coming! Thank You! We’re incredibly grateful for your support during this early stage. Every bug report and suggestion helps us create the best game possible. Together, we’re building something truly special. If you encounter any issues or have suggestions, please share them in our Community Hub or join our Discord server. Your feedback is crucial, and we’re always here to listen and improve.
