An intriguing puzzle game with a relatively high level of difficulty.

The last image shows the solution—please view it with caution.

This is not my original design; it’s a replica of Yuu Asaka’s product of the same name. The original version was quite expensive, so I couldn’t bring myself to buy it and instead 3D-printed one to enjoy.

If you can afford it, please support the official version.

Due to the inherent characteristics of 3D printing, the surface textures on the two sides of the finished piece differ significantly, making it easy to identify which side should face up during assembly and thus reducing the overall difficulty. Therefore, we recommend sanding both sides after printing to achieve a more uniform appearance.
