Hahaha thanks a lot! I´m happy you enjoyed the game! I played it myself another time and I get now what you mean by the ammo not decreasing! That mechanic works as intended, but it´s not really clear. The gun doesn´t decrease your ammo, but the shotgun and the minigun do. You can buy them and then equip them with the 2 (shotgun) and 3 (minigun) buttons. Thanks for the feedback.
