Time's Tower: Unsinkable Starship

Story:
Deep space, 2222.
You're a mechanic on board a ship known as Time's Tower... A ship you know absolutely nothing about. For example, why are they so deep in space? What are they carrying on board that's so important? Why is it called Time's Tower? As you walk around the ship wondering these questions, a mysterious object hits the ship and causes it to crash-land on a nearby planet.

You wake up in the harsh, dry desert, with nothing in sight but a huge sandstone building. You walk in to find a ghost before your eyes. Are you seeing things? Apparently not, because this phantom isn't going away. In fact, he wants to join your team. He claims he is a "learner spirit", that is, he can learn abilities from other ghosts. You and your new friend now look for the sunken ship and the rest of the crew on the planet.

The mechanic alongside the Learner Spirit.

 

Meanwhile, strange humanoid like creatures are trying to get a hold of the crew and whatever was inside Time's Tower. It turns out in the end that Time's Tower is a holding facility for a time traveler spirit, kept in space to prevent anybody from reaching it, including enemy governments. The mysterious object that hit the ship was a missile from an enemy ship. When the crew tries to get away with the spirit, their captain is shot and killed. The learner spirit finally learns his last ability... Time Travel. You and the crew go back in time and manage to stop the missile that crashed the ship from ever being launched. Time reverts itself to an alternate timeline, in which your crew never learns the secrets of Time's Tower.

A final shot of the planet's surface is shown. A kid is seen sleeping within the sandstone structure you entered at the beginning of the game. That kid was your learner spirit.

Gameplay:
The game is a platformer with backtracking (a metroidvania). As you fight bosses in the game (spirits), your learner spirit gains new abilities to help you get into places you couldn't get into before. Your goal is to collect pieces of the ship and find all of the crew members so you can pilot a make-shift ship back into space.
