Was expecting this to be yet another visual novel at first so I was pleasantly surprised when the black screen not only changed to show some 3d models but then also goes to some gameplay.
The mini-game itself was fairly enjoyable, I think my only complaint would be in one of the last levels the target button was completely obscured by the walls and I had to guess which of 3 possible squares it was in.
Similar to KimariDev I didn't get the connection between the story and the gameplay, I think the way it is at the moment I would have probably preferred it if either all the time had been put into the visual novel side or the mini-game side, instead of only a little of both.
