Hey great game with a cool concept. I really liked the graphics and sound and they mesh well together. Rare to see something so cute yet so destructive, sudden music change from calm to crazy underscores it. The screens and interfaces are pretty and effective.
As for parts that could improve, the gameplay itself is pretty single tracked and could really benefit from something that gives variation. Maybe you get energy from eaten planets and can use it somehow. Also the lack of indication on if you're close to choking, nice idea might be to make Noctus look more stressed the closer you are to choking. Something to show progress would be nice too.
Anyway, nice game, enjoyed!
