Witch Explorer

Witch Explorer is a game which features a mix of both shoot 'em up and tower defense gameplay. You play as the witch Tia, who is on a teasure-hunt in order to remove her debt and improve her magic shop. The goal of the game is to defeat waves of monsters by both strategically placing units on the map, and by flying around on the map while shooting and dodging projectiles and enemies yourself.

Tia's magic item shop is carrying a lot of debt, to the point that parts of the building and precious grimoires were used as mortgage... In a land far away, rumor has it that untouched treasure lies in an uncharted area known as "The Cave of No Return," where dangerous monsters live. "We will be able to buy back everything if we get our hands on the treasure!" Tia and Doll, the magical lifeform she created, are embarking on a treasure-hunting adventure!
