BACK TO THE FUTURE

Our time machine has broken down. To repair it we need to acquire some parts that can only be found in different time periods, otherwise we may never be able to return to our present in 2122. Visit the different eras and pass the tests to collect all the parts. But be careful, if you falter during the search, the temporary doors might close, making it more and more difficult for you to return.

The fuel will be topped up by finding the missing parts.

congratulations!

You've succeeded in acquiring the replacement parts needed to repair the time machine. You are now cleared to return to the year 2122.

The time door has closed, be careful or you will not be able to return to the present.
