The game got my attention just because it was made with Copper Cube 6. As a fellow user myself, I was invested in the gameplay and story. It was unique, simple and the performance was great. I would say the only thing, which would elevate the game are visuals and overall use of assets. Prefabs are easy and fun to use, but they provide less adventure. If this game was made with different set of materials, it would definitely benefit and become more recognizable.
Overall, the game is amazing. I will be looking forward to updates and future developments. Best of luck. Cheers!
