I appreciate the feedback. Unfortunately we do not have control over the configuration window as it is a unity default standard. We left it in so that the player could choose which resolution they wanted to play at, as well as if it was in windowed mode or not. Our game will automatically resize to the resolution you choose and was tested to work with a 16:9 aspect ratio. We also did not intend for the player to use any other buttons or remap any controls as the theme was space, so naturally we only wanted them to use the 'space'-bar. We were debating on making the giant white arrow that points towards the end of the level flash so that the player would have a better sense of where to go, however this was scrapped because of time constraints, but we would love to add it in the future! Thank you so much for your feedback, glad you got to play our game!
