I do not know how, but you managed to break everything in general. Although you are certainly not to blame for this, I have thought through too little of everything.
1. Due to the fact that your monitor (1280x720 or 1024x600 as it seemed to me), the canvas created for the 1920x1080 screen just broke, you literally did not see most of the UI.
2. Some things also somehow refused to change their speed, which is why you had an increased speed in the underwater scene.
Your video is currently the biggest bug report for this game.
I hope that these mistakes did not upset you too much and you got positive emotions playing my game.
