The concept itself isn’t that uninteresting, it is indeed very unique, and not in a bad way. But the art is practically non-existent. And when you see the title screen breaking down, if you don’t go fullscreen, you just know, that the game wasn’t that polished.
It is indeed important to have a solid game mechanic, but if everything around it is forgotten, the game that you get isn’t enjoyable, either.
Previously I said that you didn’t tell us the controls, but they are actually in the description, so I rerated it.
