DiXidiasoft invites you into the Victorian age to retrieve Nikola Tesla's stolen invention!!

The Steampunk League is a 3D isometric action platformer set in an alternative Victorian Age, revolving around the story of Nikola Tesla and his eternal rival Thomas Edison. In this universe, Tesla managed to get rich thanks to his inventions, leaving Edison on the edge of bankruptancy.
When the entrepreneur steals Tesla’s secret invention, he has to retrieve it together with his comrades: H.P. Lovecraft, E. A. Poe and Ada Lovelace.
The whole story takes place in four epic cityscapes of the Victorian Age.
Travels around the world to ruin the Edison's plan are waiting for you in the Worlds' big cities and the deepest caverns, the English countryside and the ice that only Russia can give, cross the Brooklyn Bridge and walk into the immense Louvre, there are many places to visit, and only with your will force you can get as high as possible, up to the moon. Explore the most beautiful cities of that time, reinvented in steampunk sauce!

Face the levels across mobile platforms, slippery floors or sticky platforms without falling into the abyss and don't get crushed by mechanical presses. Then, avoid traps and poison and the puffs of fire of the forge. Pay attention in tackling levels, everything is against you.
You can play up to four different characters, everyone with his own peculiar abilities. Decide who to use in order to face the levels, choose from four of the most famous historical characters, fight in the shoes of the inventor Nikola Tesla, or choose to use the dark magic of the writer Edgar Allan Poe, fight hand to hand with the detective Howard Phillips Lovecraft occult or use the little robots of the scientist Ada Lovelace. But there are many other historical characters ready to help you against the enemy, Thomas Alva Edison, and his famous companions.

Be cautious: thanks to Edison’s huge army, your quest it will be much more difficult than you think! Violence is not always the right answer: you will have to tactically plan your moves to overcome the threats waiting for you.

Race to complete the level as fast as possible or take your time to explore the environment, uncover the secrets hidden in each one!
But be careful, powerful enemy are waiting you into the darkness
The game features a very detailed handpainted style optimized to get a cartoon-like result.

We used many references to take inspiration and reinvent the most beautiful cities of the 19th century, making them unique and adapted for the cruel platforming waiting for you there.

Will you keep us updated on it?

My internal nerd is pleased already. Definitely following this. On Facebook too I guess.

- Will we be exploring large maps, or is it a linear game ?
- Do you usually have to go from point A to point B, or do you have missions to fullfil ?

- Does each character have specials powers based on their persona (Tesla has lightning stuff, while Lovecraft can summon demons, or something) ?

- Do you choose your hero at the beginning of each stage, or do you make them cooperate, does choosing a hero change the level in terms of scenario, enigmas, etc.

- Is the game filled with references and trivia about all these famous characters ?

I'm surprised at how good this game looks. So is a puzzle heavy game or more to action?

• Ogre's anims are choppy, add more frames.
• ... also check the alt palette, one of those colors is out of place.
• You also might need a better alpha for his hair, I know it will make it a bitch to paletize but ATM you can see the individual hair planes, which makes it look like he's wearing one of these on his head.
  
• King is nice, just add some micromovements on his hands and he's done. If you want me to nitpick, his mask texture could really use more contrast - right now it's kind of a messy blur.
• Oh, and you might want to cut out that light you put next to the camera - King's right hand is projecting shadow onto his left hand, and Gogo's chain does the same onto her legs and torso. This makes the light source seem inconsistent - as if they have a spotlight pointing at them 24/7.
• Armor King's stance might need to be redone though - not much wrong about the render (just the 'plastic' mask), it's just the animation that doesn't look right. Oh, and you got the contrast OK on this one.
• Gogo kind of needs work - her hair planes have weird physics and clip with her shirt, her jacket material is shiny, her chain is extending in her hands between frames 1 and 8 (looks like some weird gravity going on), her skirt texture makes it look like a pair of pants, her left wrist is stiff (it shouldn't, considering she's holding quite a weight)... and worst offender of all, the chain in the left hand is not affected by physics at all!
  
• Raijin's standing actually looks almost finished, just fix his scarf going through his drums ring and add a bit of clenching to his fists and he's done. Honestly, he doesn't need more movement (maybe some jiggle in his hair and some wind blowing through his scarves if you really want to add more)
  
• Mokujin is nice, I think I have nothing to what is going on with his left ankle from frame 15 onwards
  
• Kunimitsu's good as well.

i already reviewed spo ryu. please be more specific

• increase the animation frames on starting and ending movements
• reduce the actual swinging time so that it looks quick

• 2 frames for startup
• 1 single frame for the actual swing
• Rest of the animation is dedicated to going back to stance

• 2 frames startup
• 2 frames swing
• Rest of anim is going back to stance

• The blade of the sword uses too many colors on its own, you might share them with skull on his belt. The golden part on the hilt might share colors with the golden parts on the armor.
• Do you really need two different shades of white? I mean his white glove and his sword hilt. Just use the same shade for both and you'll save yourself at least 8-10 colors you can use somewhere else. Trust me, it's not noticeable unless you purposely look for it.
• About his belt, use the same colors as the circle thing on his back, just shaded differently so that it looks like a different material.
• On a second thought, the color on the grey part of his armor might look better for both of said parts. Just give it a few tries and see what works best.
