Are you sure you’re using delta time with your game logic? By the time the fuze is done it’s already far in the sky and unable to hit anything besides larger planes right above me. The planes also make short work of me in mere seconds.
I’ve included a video to show you what I mean. For reference my monitor is 360hz, which if you were targeting 60fps would be a 6x speed increase. If you’re using a built-in engine timer for the fuze it might use different logic from the rest of your game.
Otherwise it looks good! I’d love to try an updated version of the game with this bug fixed, if you plan on working on it some more.
