1047, less is more.....
Let me explain. Also this can be slightly opinionated...
Your game is currently too easy to learn and play. The movement, shooting, maps... Are too easy... Fun? Sure..for how long?..
Idk... Not long to me.
Don't like to use other games as examples but when you look at some of the most popular games ie Pubg csgo valorant league.. again opinionated ... They are easy to learn hard to master... They have that right formula .... Getting precise movements combos... Map awareness. Etc etc..
You're going to keep adding more fun fun fun fun fun. But for how long will this last? Less is more idea comes into play
Build a core that is easy to pick up but very hard to master and you may have people wanting to eat more.
