Here it is. Space travel. Great game.
Although the construction time is short, the game does not give a pause for the launch until the "ready" button is pressed, which could be added or just launched after the construction has started - it will just launch in a loop.
Maybe that's the idea, but still some pause would be appropriate if you didn't intentionally do it without pressing the Play button, but it changes the experience of the game. In any case, this is just a suggestion. And these are my thoughts, and the game can be developed in many ways.
