Really fun actually if not a bit grindy.. but grindy in a oddly calming way. Like mining in minecraft, all thats missing is some really calm music and maybe the occasional thought dialogue from the robot. The objective is freedom but it would be really nice if the robot spewed out really deep thought bubbles here and there.
Managed to get all 4 endings. The 4th one is pretty sneaky but I was using the gem trick the entire time and after discovering the 1st ending it immediately pointed me in the right direction for the fourth. Really natural progression there actually.
Good Job :D
