I'm looking for a game that is about protecting a Gem or a diamond, where the protagonist is a wizard wizard but I think it also has several characters to choose from, but the one I remember most is a wizard wizard, where at the beginning of the game gives you the option to create a castle or a pavilion where there goes out soldiers and you go in search of resources both trees and stones and at a time and comes the horde of skeletons I think, and various skeleton form both large giants and all kinds of monster. And at the beginning of the game, protect the Gem diamond and shoot lightning to protect yourself. Also then you can create walls to protect the Gem or the diamond. It's super pixelated, it's from top to bottom the scenery and it's very pixelated very pixelated. It is primarily a forest, but the scenery is random. It has desert, snow or forest
