Hi! My name is Shoma. I'm from Japan.
I'm crazy about 'lateral thinking puzzles' recently.
I tried to make the game with that idea.
I made a simple puzzle game that is able to be cleared super very short time like a 5 minutes.
The title of my first work is 'I misplaced the key somewhere..' .
The purpose of the game is 'back to the spaceship before the oxygen runs out' .
STORY
We came to treasure hunt by our spaceship. I misplaced the keys somewhere while exploring in outer space and couldn't enter the spaceship! Oxygen disappears moment by moment, and the members say die ...

There is the answer in one screen.
If anyone can solve this mystery, please report it here. - Don't write the answer；)
please try it!
