The game is pretty enjoyable. The art is ok but definitely needs more variety, the "soldiers" don't have a skin, and the game is honestly a little too dark. The lighting effects are good though. The sounds in the game were good (but the zombies make sounds way too often), and there is no music in the game.
The gameplay is just a simple top-down shooter, I feel like the game would've been a lot more fun if it was more difficult, the zombies needed to be a lot stronger, faster, and more in numbers, especially with the 2 AI companions that are with you. The AI script is quite good.
There were not many bugs in the game, only that if you got too close to a wall, your gun would stick out of the other side and you can shoot through it. Also, The mouse aim controls were not the best, I believe the better way to implement this would be to make the character point towards the mouse pointer, not make the character turn with the horizontal mouse movement.
Overall, a good game that could have been a lot better with some more development time. Good luck with the game jam.
