Fun experience, it reminded me a bit of classic Resident Evil.
I loved the radio commands the most, I thought it added a bit of charm.
The core gameplay loop is actually surprisingly solid and feels good. The scarcity of ammo forced me to learn the optimal number of shots to fire before I can finish of the enemy with melee. Having a sprint was a nice touch because it allowed me to run away and try to regain the advantage in bad situations.
My feedback if you choose to keep updating the game, is to make the melee more punchy and juicy. For something so essential, it doesn't feel good right now and lacks game. Also maybe make the ui larger, it is so important when you need to keep track of ammo.
Nice work, had fun playing it
