The game isn't very hard or long but can be tricky at times.
Minor spoilers below.
  
# Early Game  
Focus on gaining levels without using too much magic.  
Avoid fighting the 4 drones, farm the Donut/Saddle duo instead.  
Once you are level 5 and with a few capacitors to spar (to trade for Magic Crystals and Repair Patches), you're good to go for the first boss.  
  
# Other Battle tips
- The Reserve skill let you stack a Magic Attack buff up to 3 times. It's usually more MP efficient than using magic skills multiple times.  
- The Dodge skill can also be useful when you expect an enemy attack.  
  
# Access the hidden stage
Before the final battle, go back to the Reception near the beginning of the game and some events will occur.  
Figure out the rest.  

# Access the hidden stage (Ver 1.3)
To access the content, after destroying the power plant, go back between the first and second area (before the Waterway), where a passage was blocked above the fountain. You'll now be free to access it.
  
# Puzzle Hints  
## Research Building Code  
There are 5 offices, each with a certain number of potted plants.  
And you must provide a 5-digit code to the Crane Room door...  
  
## Culture Area Cables  
Probably the most obnoxious puzzle.  
From my understanding, it's akin to a Ladder Game.  
However it's not clear from which side and where it's supposed to go.  
I'll put the solution at the end if you have troubles.
