If you're using a keyboard, you're always going to have a harder time than using a gamepad. Buggy Game is a simulator, which means you often want to add 'a bit of throttle' or 'a hint of steering' and that's just not really a thing on a keyboard.

For gamepad users who still have a hard time steering; I noticed that many (most?) people steer by simply moving the analog stick left and right (sounds logical, right?).

But personally, I find it way easier to control by keeping the stick fully forward, and then making a half arc left and right when steering.

This gives you a more grounded feel, you can exert more pressure which feels a lot more stable. Give it a try!

When in doubt about opponent movement or what corner lies ahead, just release the throttle a bit. This will move the weight of the car forward, giving you better steering response. It's perfectly okay to coast a bit while reorienting, if you still press the throttle slightly, you will hardly decelerate.

Be patient. Staying behind an opponent for a minute is totally fine. Wait until an opportunity arises to dive in besides them.

When you're almost out of health, just prioritize driving very carefully. It's okay to keep your position instead of push - simracing is about discipline and restraining yourself, more than sheer speed.

It's totally okay to not win every race. I'm the developer of the game and I finish around 3rd on average!

If you keep on dying during the campaign, there's no shame in enabling 'weenie mode' in the gameplay options, to enable retries. Well, a little shame, actually, but nobody has to know, right?

Good luck!
