Spellcasting action roguelike Wizard of Legend is a free PC game via the Epic Games Store, so claim this pixel-art dungeon crawler quickly.

One of the better unknown games I’ve played. It’s free right now. Give it a go if you like rogue-like/souls-like types. Very rewarding gameplay (and pretty difficult).
