Very bare-bones top-down zombie survival shooting game. You can:

• Shoot zombies and get points
• Use points to buy weapons, ammo, and power ups, and unlock doors
• Find a car and take part in a time trial

This was made totally bare-metal, without any gaming frameworks or any JS frameworks at all. There’s much to do to make it a decent game, but most of the code is very old and not in great shape. I started it years ago and just added bits now and again for fun. Rather than refactoring, it’d probably be better to start again with Phaser or something similar, make a more well-written and extensible base, and just pull any salvageable bits from this into it.
