Thank you for your feedback brother! The "D" restart button is a mistake that I accidently left in. Whoops. The tile map issue you are addressing in your second point is a new glitch that I have to troubleshoot and fix. As far as point three is concerned, I will do my best to improve user experience and game feel without hindering game flow.
Again thank you for your valuable feedback! If you haven't already, please feel free answer some questions about the project:
