Evaluation
Acro FS entered Steam Early Access on May 23, 2018 and remains in that state today. Only two developer posts have ever been made: a day-one bug fix on May 24, 2018 addressing controller setup, and a feature update on October 10, 2019 that added three new aircraft, three new flying locations, and multi-USB controller support. That October 2019 post is the last known communication from Knife Edge Software — there have been no further updates, patch notes, roadmaps, or announcements of any kind since then. The game has no announced 1.0 target date and no stated plan for completing Early Access. With over six years of silence from the developer and no indication of whether development is continuing or has quietly ended, the game's future is genuinely unclear.
Evidence
Feature update adding three new aircraft, four flying locations, new race courses, leaderboards, and multi-USB controller support. This is the last known developer communication.
Day-one post about controller requirements and setup guidance, noting multi-USB support was not yet available.

About this game
By Aviators, For Gamers
Acro FS is a stick-and-rudder aerobatic flight simulator created by Jim Bourke, airshow pilot and member of the US Unlimited Aerobatic Team. Designed from the ground up to accurately simulate aerobatic flight, it allows you to experience what it’s like to strap into a high-performance stunt plane and take to the sky. Take control of an aerobatic airplane, throttle up, and discover what you can do. There’s no navigation, no radios - just a lot of horsepower in a state-of-the-art aircraft.

Controller Required!
Acro FS requires a controller to fly. For good control, you'll need a 4-axis controller. A gamepad will work, as will "3D" flight sticks that include pitch, roll, yaw, and throttle. For best results, you can also use an RC-style controller that places these controls on two sticks, or muliti-USB systems with stick, throttle, and rudder pedals.
