Do you have any concept art yet?
not rly, I mean I have rough sketches here and there, but they're not really for show off, but I'll have more to show when I finish some locations
What genre is the game? FPS? Roguelite? Grand Strategy?
point and click adventure
what technology (game engine / own stuff) you will use?
Add a skinny tower which has an elevator that takes you to the top and then flying ships underneath you and you have to jump at the right time or you get squished. Add phaser guns to shoot enemies. Add multiple planets and a market that you can buy things at and an open world option which lets you just go around and explore. Add ai's that talk to you like a VN. Add underworld. Add music. Don't use GTK!
