Thanks for your honest and complete feedback! The wheel and sliders were the hardest thing to make since when you click on them you need to keep your mouse over it all the time. And for the difficulties, there were added the last hours, meaning that I couldn't change much between them. I wanted to change the camera speed and rate at thing are disrupted but my system couldn't endure that ( bad coding for the most part). For the game mode with escalating difficulty, it the thing you unlock with nightmare mode. And thanks again for you rating my game and leaving a so constructive comment!
