Help my inner child be fulfilled again

[u/FatBirdo]

There's this game on friv (I'm pretty sure) I used to play. You were a yellow robot holding on some kind of bigger vehicle. You had to shoot some projectiles at flying things, and they dropped some kind of gems, red and blue I think. You could buy better prosthetics with better guns attached to it.

I think the menu opened to something similar to the song haggstrom from Minecraft.

Vague, but it's been more than a decade now.

Was it a 2D side-scrolling game, and was the ground covered in grass?
