congrats on finishing your first game! Making a game from start to finish is no small feat, and I can tell you put effort into it! 🎮💪
Since it's a top-down shooter, I think improving like enemy AI, shooting feel, or visuals ,could make it even more fun by adding more obstacles bc it feels boring rn, . Maybe adding 4th dimension and quantum simulation would help bring it to the next level! But that's very simple for u xD!
That said, first games are all about learning, and this is a solid start. Keep making games, and you'll improve so much with each one! Looking forward to seeing what you make next!
