I really liked the manual reloading mechanic because it makes you think twice before committing to a gunfight. I feel that mechanic has the potential for a full survival game. The only thing is that I didn't know which bullets were used and which weren't, so I had to use all of them, extract all the bullets, and insert new ones. That process takes a really long time, and worse if multiple zombies chased you.
I couldn't slide because my hand didn't reach all the keyboard keys at once, so controls must be optimized.
Overall, I nice well-implemented idea.
and the controls part I need to learn to add key binding. Thanks for playing glad you liked it :)
