Gonna be totally honest, I could not figure out how to "play" this game, even reading your description over and over. I see nothing happening on my screen but my money keeps going up. I'm guessing this is an idle game and my ships are delivering automatically? I don't understand the significance of the "Red" systems.
When I first clicked on the other systems, the default zoom level is like super zoomed into the Sun, I suggest starting it out zoomed out view view of the entire system.
I can purchase things but I don't know what any of them do. Am I supposed to build more "stations"? How do I get more "ships" beyond the 4 ships? I have Eagles researched but I can't buy any more of them since I had 4 ships.
Apart from the gameplay issues, really nice job with the aesthetic, and the UI style fits in quite well too.
Edit: OHHH okay I finally get it (after like 15 minutes). I needed to scroll down in the "builds" to see the option to buy more stations and also more ships. I also see the ships now, but they are TIIIINY and so hard to spot.
Suggestions: - Ships and stations need to be 1000% more visible. Perhaps they need to be bigger, or different color against the background, or have trails drawn behind them. - Make the UI windows longer and also display a scroll bar if its scrollable - Start the game out with one "system" and inside that system, until the player has some idea of what is happening. On the 'overworld' screen, you can't see anything progress or move, so that just adds to the confusion. Maybe unlocking other systems can be a research item. - Don't progress the game until its made clear that the player knows what's happening by their actions. I didn't do anything, so I shouldn't be making money, and systems shouldn't be turning red, because I'm still figuring out whats going on. - Perhaps make it so that the player needs to set trade routes or something, so that their action is what sets the deliveries into motion?
