Droplet: States of Matter

About

Droplet: States of Matter is a 3D platforming action adventure game inspired by the old school classics of yesteryear. Find yourself in the colorful, cartoonish Periodic Table Universe where elements, compounds and other scientific phenomena are personified! Play as Droplet and his sister Molly-QL, a duo that can change between the four states of matter.

At the Galactic Science Festival, the famous scientist Professor Humphry Heisenberg Otto invents a weather machine to help better the lives of the peaceful people of planet Eich-Tuo. However, his old, vengeful colleague Dr. Ruby Dium returns, claiming that the professor stole her research. Things only get worse when she invites the nefarious Lord Krypton to seize control of the weather machine. With the entirety of Eich-Tuo’s climate now at risk, Droplet and Molly-QL must take it upon themselves to save the galaxy!

  • Water form is your default state of matter with well-balanced stats and the ability to swim underwater.
  • Ice form can freeze the surface of liquids to walk across.
  • Cloud form can leap great distances and walk on top of clouds.
  • Plasma form can activate switches that reveal hidden paths made of hardlight.

  • Explore 30+ levels across seven star systems. The Noble Gas Kingdom has lots of secrets to find and enemies to defeat.
  • Face off against 7+ bosses. Use your states of matter to punch, kick and shoot them!
  • Navigate seamlessly between first and third person views. You can even freely move in the first person view to play the game like a first person shooter!
  • Switch between playing as Droplet and Molly-QL. They are identical in moveset but have their own pools of health and ammo. Pick your favorite or use them both!

  • Obtain quantum crystals to explore other worlds. Find them at the end of levels, off the beaten path, by completing time trials or by gathering 95% of atoms in a level.
  • Collect atoms to exchange for ability upgrades. This can be anything from increased health to an increased amount of time staying in one state of matter.
  • Find the twelve lost artifacts. If you have the cunning to seek them out, you can turn them in to Dr. Form Al DeHyde for a hefty reward of atoms.

  • Meet a large cast of colorful characters inspired by scientific puns. From the likes of the dastardly pirate Captain Salty Peter to the grouchy middle manager Sill E. Con!
  • Watch out for 100+ unique enemies! Some of them are immune to certain states of matter so you’ll have to keep on your toes to figure out how to take them on!
  • Witness cinematic voice acted cutscenes. They are fully animated with lip syncing!
  • Listen to nearly three hours of original music. Additionally, the title screen is a full-on music video for the song “Through the Water Cycle”, featuring lyrics synthesized with Vocaloid!

Do you have what it takes to save planet Eich-Tuo? Then let Droplet and Molly-QL take you for a ride through the water cycle!

Behind the Scenes

Droplet: States of Matter was developed by just one person, Karl “Krayfishkarl” Ast, over the span of seven years entirely within his spare time. Development began in January 2018 while he was in the process of learning Unreal Engine 4 and taking the leap into the third dimension. It has always been a dream of his to make a game in the style of the classic 3D platformers that he grew up. Among the primary inspirations were Super Mario 64, Crash Bandicoot, Spyro, Banjo-Kazooie and many more.

Virtually all graphical assets with a handful of exceptions were created by Krayfishkarl. The models were created and animated in Blender while the 2D sprites were drawn using Clickteam Fusion and GIMP. Most of the game’s textures are heavily modified marketplace assets and public domain images to hone in on giving the game a unique visual style.

The game’s soundtrack, which is almost three hours long, was created using FL Studio. The title screen theme song “Through the Water Cycle” uses the Vocaloid Amy voice bank for VOCALOID5 with Krayfishkarl himself writing the lyrics.

Droplet: States of Matter takes place in the Periodic Table Universe. You may wish to read more about the world and characters in the Krayverse section.
