As the others have mentioned already, the gun system is a HUGE free model. The map looks a little bland, but since you already gave context that it is your first game, not bad!
For the map, I suggest adding props that players can jump around, for example homes, buses and streets, sort of like an arsenal vibe.
I can definitely see potential. Keep up the great work!
I like the idea of where you can go in and battle, that’s pretty cool
I really think the lighting and reflection in the game is very nice props to whoever did that!
Con’s
The name itself is unoriginal, I suggest too come with a new name
There really isn’t a point to the game, that doesn’t attract players, Add some kind of currency system or round system because at the moment the game isn’t fun to play at all
There Map is too big and bland, there is no color or anything, these are the things that don’t keep players in for long
There aren’t any GUI’s or music
The Guns are free models, I suggest either make your own, or find someone doing commision to help out, even if you want to use them, give some compensation and credit the creator of the free model.
With all due respect, this game feels very rushed in an attempt to get your first game out there. We all make this mistake in our first game so don’t feel bad :). Don’t rush to get your game out there, take your time so it can be the best it can be! With a little work this game can reach some good potential and since it’s only your first game you did well on it! This game can do well with some fixes. I wish you all the best of luck on your journey with your game!
