Hello, J club. I have the following Suggestions for you. Rocket launch smoke, according to the player's design of the exhaust, smoke emissions. This way the playability is higher. This is similar to collision data. If oil drums are used for construction, the smoke collides with data when it hits the drums and cannot pass through them. This can form a visual effect relatively shocking. Increased and greater playability. The second suggestion is, can you add some variety to the solar panels, the stretched solar sails on the international space station, and the most common y-shaped solar panels, and the fan-shaped to round-shaped solar panels? That's what I suggested above, and I hope you can add it. Thank you very much!
