I can't stand to be the last stand standing

My first ever game without just following turorials. I know its very rough and I didn't get everything I wanted finnished, but I still hope you have fun.

You are the last food stand standing. They are out to get your secret formular. Defend it or die trying.

Survive 2:30 minutes and you can gather enough time to send your formular to your children. Shoot with spacebar or left-click, your bullets fly towards the cursor. Gather ressources (yellow and red) to make food and sell that to other humans for money.
The brown car with red "shop text" on top is the shop.

Defend yourself from ghosts (white) and crabs (red). You loose if you have 0 HP or run out of fuel. Killing an sixtopus drops more fuel.
