Please fix the following issues: 1)End screen is just black. 2) "Press Enter" at the start does not work before you change the controls. 3) The controls are very annoying and not excat enough. 4) The left side of the screen is free of obstacles. 5) The upgrades should change the appearance of the ship. 6) Give the ship more initial speed so you can get easier practice. 7) Reduce the amout of money gained over time and give some chance for multipliers. 8) The game is too short and there is no "story".
