I'm trying to get a new job, so they gave me a test task with the conditions: topdown shooter or whatever you want, 2000 active objects, several static objects, collisions etc, no game engines, no physics engines. 3rd party libs allowed. Time: one week. I decide to use SFML and GLM. All other code was written less than seven days. Graphics and sounds were stolen from internet, from
www.opengameart.org mostly.
So today I was done the game, and it is Zombieland.
Enjoy!
Source code. May be it can be useful for someone new to SFML.
