This game is solid, that is until you start getting farther in the game. At one point you'll have a gems with a ton of points that just get stolen immediately after trying to fuse them with other gems, removing a considerable portion of progress you've made. The game would be leagues better if it wasn't so easy to steal such a high quality gem. Maybe making it so if a person completed your dungeon, they would steal the lowest quality gem, it's so annoying, even trying to steal back, no guarantee
