This game reminds me a lot of agar.io. It has that same sort of satisfying progression, getting bigger to eat more things.
At first I had trouble winning with the strawberry because I was attacking and missing too often, but I eventually learned to only attack when I was in range.
I thought it was cool that each fruit had something unique to them. My favorite fruit to play was the avocado, because I liked the ranged attack.
To improve, I think you should add more sound effects for when you eat something or move around.
Congrats on completing your first game jam!
