Thanks so much for the feedback!
I’d love to know what browser you’re playing through, I’ve had similar issues with my bevy games before but I chalked it up to shaders before, I’ll look into optimizing it more.
My artist kicks butt, I agree.
As for the gameplay, you can shoot the plants that grow to avoid getting too much O2, but it’s pretty precise as it’s based on the sprite and where your cursor clicks, easy to miss.
