The game, especially the pixel art, is very charming! I also like that there there is a subtle storytelling of a monster bursting out of its tank and consuming all the humans on board, which adds on to the "consume" theme. But I find the movement and controls to be a bit frustrating. For example, it is hard to make turns precisely with only the left and right arrow keys. Personally I find the gameplay to be a bit boring, but I'm not the biggest fan of simulator games so there's that.
Kinda depressing that the humans get killed immediately as soon as the little roomba approaches them.
