Eh…

It’s cool watching the rats get stuck or find the food/water units

rats exist

this is incredibly realistic as rats exist in real life. i can only imagine what the creator of the simulation was thinking when they created it. i myself have seen rats in real life and can confirm that they exist. i once saw a rat in the side of the road it was eating the grass. i think this game could get better if there was a slider to choose how many rats and food things there are, with an advanced thing that lets you pick more. a joystick and zoom options would also be great to be able to see the rats easilyer. it would also be cool if each rat had a slightly diffrent color or pattern so you could kinda tell them apart. also zombie rats. this game could also have the feature of rat names. they could be named rat 00001 and rat 00002 to start but if you select one you could change it to a diffrent name and watch that rat as it moves around. my last suggestion is to add a controlled version where you control a rat and have to fight to not get thirsty or starve. this could allow me to see what it is like being a rat. i think zombie rats would be cool.

Interesting concept game

I like the funny idea of overpopulation. It will be better if there are more attractive graphics!

👍👍

The game is good and easy to play! The concept is also very interesting, perhaps you could try making the text larger for better readability.

It’s relaxing watching them.

The soft grey and pink colors of the rats on the white maze offers calming and relaxing mood. I found myself being attracted by the unique path of each of the individual rats in their busy daily lives. 👍
