Original Description:
Here is a small survival game I made in which you must defend yourself against zombies, as if there weren't enough zombie games.
The controls are listed in the instructions page which is short and takes less than a minute to read.
In between levels, you may buy new equipment, ammo, and other supplies.
The title is an homage to the Meteors song "Half Hour Until Sunrise".
As the title says, there are seven "hours" (levels) in the game, each increasing the zombies numbers, spawn times, and strength.
I hope you like the game. Thanks.
Edit: I'm giving you some ammo to start off with and I'll tone down the aiming margin. I wanted it to add a bit of a challenge, but it can end up being a bit annoying.
