Nintendo Switch:




I just wanted to let you know that this demo is dated and differs quite a lot from the current version. I probably wont release another demo before releasing the final game but I still feel like this demo is fun and gives you a good idea about what the game is all about.

I hope you enjoy it and please visit my dev log for the current status of the game: https://forums.tigsource.com/index.php?topic=60261.220


The Lost Light of Sisu is a heavily physics based puzzle platformer set in different alien environments.

You are on your way back home when the ship loses its energy. Because of this you need to land and search the nearest planet for a new source of energy.

After beaming down, you find energy cubes that will power your ship, but also change your abilities.

To collect all of the energy cubes, you need to use these level-temporary-abilities and solve physics based puzzles.


You can move left, right and jump. You can also roll up hills and cling to walls.

On each level you need to collect a certain amount of energy.

This energy is radioactive and affects your abilities.

To collect all energy cubes, you need to use these level-temporary-abilities and many environmental physics based systems.


  • Character is fully affected by realistic physics.
  • It's a mix between a platformer and a puzzle game.
  • The energy only alters your abilities for the duration of the level.
  • Using physics to create interesting solutions and gameplay.
