Yes i agree with you.Problem only have 2 days and with Godot engine particle system effects working strange in web stuff i dont have much time.I will definitely keep this in mind later,maybe will update game after jam,or make a separate version.
And about color - it is matter of taste.For me this is nice colors.I agree what blue will be better for walls,but i want to make something in style of matrix colors.So yea,maybe will be adding different color schemes later? Will see.
Thanks for feedback,appreciate it!
