This game has a good start! But it's missing a few things that make it interesting, let's go over them:
The Good:
You've got a good core mechanic going on, the rotating weapons. And building upon this will bring your game to great heights I feel!
To improve:
However, in hindsight, this game is basically still like any top-down shooter. The rotating weapons do not add much to the game if they have infinite ammo. I have one suggestion as to how I'd add more dynamics in the game:
- Modify the weapon rotation system so that it only rotates when a weapon runs out of ammo
- Once it runs out, the player will throw the gun and rotate to the next weapon.
- Weapons have effectively 1 clip worth of ammo (like 1 burst of SMG for uzi, 6 shots for pistol, etc.)
And finally, this is where things become interesting:
- Enemies drop weapons
In doing this way, players have to both 1) manage their ammo and not just wanton-fire everywhere and 2) adapt on the fly to the weapons they have on hand. This will also inevitably introduce many unique enemies, which I think will add to the game.
This will most likely not be the most perfect suggestion: because it's only a suggestion to cover the greatest weakness of this current version: the lack of urgency and dynamic gameplay. If you want to tackle this issue in another way, go for it mans.
Great start!
