Thank you very much for your suggestion. A decent story or setting will definitely make it better. I will try to add one.
It reminds me of RED CODE. It’s a flash game with a split-mode (using your landed ship’s turret, or going out on foot). Might check it out for inspo!~
I watched the gameplay and it gave me some ideas for improvement. will try to play it myself later. Thanks again, I really appreciate it
