The idea behind Mine Defenders is a tower defence + auto battler. The player can mine out the map which is randomly generated, then in mining can uncover enemy spawning pits. The player then can choose to place down their defenders who will fight until death. In combat the defenders will gain exp which was going to be used to unlock skills and more attacks. What is shown here is just a small prototype. Out of all the projects shown in my portfolio this one is the oldest. And so this one was the only one which I didn't apply rapid prototyping, and you can see how it makes such a difference in terms of development time and results.
