The game is exceptional, you nailed the pace, style and the art work is stunning. Probably, the coolest arcade retro racing I ever played.
But there's an issue, the input bindings that come with the game generated conflict when you remap them. Even when you select button "A" and "B" for throttle and brake, it doesn't cancel the D-PAD action, if you press "Down" in the D-PAD accidentally while turning Left or Right, the brakes will be activated, that makes the game unplayable on Steam.
Playing here on the page there's no input binding conflicts, it enables me to customize the buttons without any problems. On Steam if I choose to remap the buttons using apps likes "AntiMicroX" it will generate conflicts and double action, because the game has default bindings.
I hope that helps, I'm looking forward to play the full version on Steam.
That's how I remap it on AntiMicroX:
(I want the "Down" on the D-PAD to be my Nitro button, but when I press it on Steam, the car brakes and also releases the nitro, that's an example of the double action/conflict)
