The concept of the game is fun. I agree with other comments that there should be a gentler introduction with very easy levels.
The graphics are way too much! It doesn't make much sense that a minimalist cube game would melt my computer down. I was getting insane input lag, single-digit framerates, and the motion blur turned everything into a puke fest. It might run well on my desktop computer, this laptop is a bit older, but I have a dedicated GPU and yet it ran like I was trying to run Destiny on Ultra. Is this just default Unreal graphics profile or did you crank it up?
