How it feels

A calm and unhurried process of assembling and customizing model kits at your own pace.

What players say

Players enjoy the relaxing, tactile process of assembling mech kits digitally, comparing it to building Gunpla. However, they are frustrated by the lack of cloud saves and the inability to save mid-build, forcing them to finish a kit in one sitting. Some find the mech designs boring.
