around 10 hours for the tracks , 30 hours for the gravity and the input (with the camera and the malus with in the final level). For the portal at the beginning it took me a whole day. I made the elevator, the first and the end level in two days. I was help by a friend for the map, the menus and the navigation system of the bot. That was quite intensive, I think I should sleep now : ) . Thank for the comment, it makes my day. Accidently there is a way to Speedrun the game with ctrl and shift but I can't say more .... 😆
