Hi!,
My name is Ima and for the last year I've been working full-time on Backpack Twins, an upcoming single player platformer with puzzle elements for PC, where you must switch between two twins in order to solve puzzles, move forward and survive. 

The game features challenging but fair platforming along with carefully designed environmental puzzles.
Backpack Twins is easy to learn, but hard to master!

A few notable features:

• Difficulty increases progressively with each level, as new gameplay elements are implemented.
• Precise and responsive controls.
• Many collectibles to find. Even if you've solved a puzzle once, you may
  need to find a different approach in order to get the collectible.
• Speedrunner-friendly: Best and last times for each level (and also the
  number of deaths) are saved so you can keep track of your progress.
• Optional single-handed control schemes.

Demo available at:

Were you able to beat the demo and get all the collectibles in it? Let me know!

Comments and feedback would be greatly appreciated!
Thank you in advance for your support!
