PixelJunk Monsters - How to buy bombs from the shop?
In PixelJunk Monsters, you can unlock Remote Mines after completing the level, Gati Gati Special 3, which cost 5 gems.
But I do not see the option for buying these remote mines in the store. You can see, every other unlocked upgrade here has a price and you can buy it (except the potion, which is always active). Clicking the bomb icon (blue ball-like object with red on top), however, does nothing. Yet clearly I have enough gems (11 here).
How do you buy Remote Mines from the store?
