Reactor Countdown
The timer is ticking... you have to stop it!
WARNING: DO NOT WALK STRAIGHT INTO THE REACTOR CORE WHEN YOU GET TO IT!!!! You're supposed to flick the levers on the nearby sign instead!!
**If you hear a loud explosion sound, it means you lost!!!**
You were sent by Sneevil Inc. to go down and fix their expensive reactor which is going to explode and destroy the whole facility in 30 seconds! They sent you because their remote controlling systems failed (it never worked not even when it was first built) so you have to go down and fix it. For some reason it is locked behind a bunch of puzzles, involving cubes, buttons, and levers. Some levers slow the reactor down to give you more time. They also equipped you with their new, untested Telekinesis Tool™, which may have a side effect regarding the scale of objects.
My first* game jam entry
