I'd also like to suggest making the bombs hitbox bigger - more often than not I missed the bomb but a few pixels, resulting in not only the bomb exploding, but also me hitting (and potentially destroying) the block right behind it, causing even more destruction than if I wouldn't have tried to remove it. Or make my bullets not hurt the blocks and give me a different tool to remove them. Or make it hurt the blocks less. Or... I'm sure you'll come up with something. :D
