Stretch Goal Unlocked: Longyan (Female)
almost 2 years ago – Thu, Aug 10, 2017 at 09:26:39 PM

Hi, everyone!

We are pleased to announce that our fifth stretch goal, Longyan female, has been unlocked!

This stretch goal adds a new miniature to the game and a new race Longyan for selection, bringing more varieties of combinations based on classes and races in customizing your player-characters.

Longyan are inheritors of the Gold Dragon bloodline, possessing tremendous physical strengths and durability. Their draconic strength is a double edge sword. The thicker the dragon blood is, the shorter their lifespan could become.

Few in numbers, they form the upper echelon of the Longyan empire established by the ‘First Emperor’, said to be the first of their kind. They are obsessed with seeking ways to extend their lifespan and increase the population of their race.

They are wide practitioners of Kungfu, the art of hand-to-hand combat and using energy or ‘Qi’ as they like to call it, to enhance their bodies. This augments their already formidable body. Few would dare to go against a Longyan Kungfu master head-on.

Pledge Manager and More

Hi, everyone!

Thank you very much for going along with us since day one! Along this path, we have heard from a lot of good-hearted people in this sphere, and we have learnt so much!

In the last few weeks, we have been engaged in fine-tuning each and every detail in our game, from gameplay rules to art works etc. Certainly, we will keep working hard to improve all aspects of our game until perfection! 

There have been quite a number of work-in-progress changes and updates in the rule book and the art works, which you could have seen and will keep seeing in our campaign main page. Please stay tuned! Please, stay tuned!

Along our path, we pick up new gears that strengthen us. We are glad to introduce the pledge manager kit, Backerkit, to this campaign, for the purpose of serving you better. Through Backerkit we can manage your pledges and charge shipping fees in a more organized manner.

Some of you have shown interests in purchasing our unlocked stretch goals as add-ons. Regardingly, we tend to be flexible, at the moment we are looking into the existing functions of Backerkit, since we are new to it, we still need to look into what to be achievable possibly in the near future, at the same time there are some principles we will stick to. At the moment, we still have faith in reaching as many stretch goals as we can within the coming last few days of the campaign. Please be with us and have faith in us that we can achieve!

Enjoy like always!

Warm regards,
Spherewalker Games

New addon: The General
almost 2 years ago – Thu, Aug 03, 2017 at 08:06:59 AM

Hi, everyone!

We are pleased to present to you a new addon, the General! 

The General is a semi-boss enemy unit. Unlike the normal enemy units, he has his own HP bar, making him much tougher to take down. His presence on the field causes all enemy units to out perform themselves, and makes the invasion force a true terror. This addon comes with additional unique rules.

He is the second semi-bosses out of the 3 that we will be launching during this campaign.
