I hope doing this jam made you gain a lot of experiences and maybe helps you improve your Game Dev skills, you have well used the theme at your advantage, good job.
Here's a bunch of things I think you could do to improve the game, it's super easy and will give more replay value to the game :
- Add a score and increase it by 1 each time we eat a human
- Add some sound effects when we eat a human or during movements
- Add a background music you can loop
There's still a lot of possibilities, it's just some ideas. Congratulations for submitting something though!
