I tried fixing the ammo issue by adding buildings filled with ammo crates but I guess they were a little too scarce. Did you like the gameplay?
Yeah! Gameplay was enjoyable. Pistols shots had satisfying sound effects and good precision making combat prety good and fast pased. Don't know about not being able to die but overal just losing some money was better decision. After all this game jam is about high scores.
One solution for ammo problem could be changing ammo from int to float and make other weapons consume half a bullet of even less per shot. Or if I get rifle my ammo is multipied by lets say 5 and all ammo pickups also become x5.
Or add meele attack as I suggested and meele kills could make enemies also drop ammo. I think thats how it worked out for lattest DOOM games.
