I already own a tweaked APK of AirAttack 1941 that links energy-recovery to gameplay speed, but it caps out too soon and crashes after extended play. I need you to rebuild the mod so I can push the action far faster—ideally up to 8× or beyond—while keeping everything rock-solid. Here is exactly what I’m after: • Deliver a new APK/APKS (no source code available) where a single in-game slider lets me select any speed from the normal 1× all the way to the top limit you can safely reach (8× minimum). • Energy-recovery must keep scaling with speed just as in my current build. • The game must remain smooth: no random crashes, freezes, or stutters even during long sessions or heavy effects. • Gameplay, graphics, and progression must remain otherwise untouched so I can play online/offline exactly as usual. To help you test, I’ll supply the current modded APK and notes on the crash scenarios I’ve experienced. Please let me know: 1. The maximum stable multiplier you expect to achieve. 2. How long you’ll need to turn this around. 3. Your price for the finished, signed APK plus a brief changelog. Feel free to mention any additional tools you plan to use (e.g., ApkTool, Jadx, Smali). Once we agree on scope, I’ll provide the existing file and get out of your way so you can work your magic.
