This is awesome, such a great interpretation of the theme. I knew I was gonna like this game as soon as I started clicking on stuff to mine resources haha. I like the tower defense portion a lot too, it's really fun to place the towers and try to defend your base. I think the idea of having the crystal be a resource that's only obtainable during the storm is great too. Unfortunately I wasn't able to really get into the game, most of my turrets wouldn't fire any arrows for some reason. I tried on the web and downloable version, but for some reason only the turrets in one part of my map actually fired arrows, around 70% of my turrets just played the firing animation but wouldn't actually fire arrows. Idk if I was just doing something wrong, but I tried to add a gif to show what I'm talking about if that's helpful. Really great job on this tho I like it a lot!
