Thanks lynndonvel :) I really appreciate feedback - and that's something that should be relatively easy to implement! I'll work on adding that in this week, and will upload a new version when ready. Stay tuned! :)
Hi again, I've worked on this and have included a sensitvity option in the main menu and pause menus!
You'll have to download the new game file, and probably delete the one you already have downloaded first. Give it a try! Let me know if this improves the experience for you :)
