Immune Response is my entry for the 2025 GameDevTV Jam. The concept is loosely based on simple retro arcade style gameplay.

You are an immune white cell defending your cells from a virus attack. You have to use your white cell to eat the incoming viruses and prevent them from destroying your cells.

You get 10 points for each virus eaten and your final score for each wave is multiplied by the percentage of your cells surviving. Each wave has a target score you have to equal or beat to progress to the next level.

There are 10 waves to defeat to complete the game. Each wave has more viruses than the last, higher target score and the speed of the viruses increases too.

Controls

WASD Keys - move the white cell
Escape - exits to Main Menu

You nailed it. Don't change anything. It is perfect as it is. I played for about 15 minutes. I am not very good at these type of game so I could not get past level 4.


 That being said you did everything right. Nice menuing system. Nice intro to the game. I love the voice at the beginning of each level. 

The speed of the white blood cell is good. The viruses dropping faster is good. It is much better than my game. So simple yet so very fun. Thanks for the great play!!!
