Doppelgänger

A loanword from the German noun for a person who is a double-walker: a supernatural double of a living person

Description

Have you ever wanted to go back in time? Maybe you wanted to correct your mistakes, ease your regrets, or change your fate entirely. What if you could, with just one catch… the you in the past is still there. And the world will not allow two of the same person to coexist. Not for long, anyways.

A Hololive fan game made for HoloJam 7 featuring Cecilia Immergreen of HololiveEN Justice.

Average Play Time: 20-30 minutes.

Developer's Note

Note that this game depends heavily on time travel and multiple perspectives, so I heavily suggest reading all text in the first two minutes or so if you are not already familiar with the genre to gain a basic grasp of the mechanics.

Tips and Tricks

This game is designed to be relatively difficult and is fairly long as well. If you are struggling, here are some gameplay tips I've found that may be helpful.

Expand to view

1. Items in the game follow causality - that is, anything done in the past effects the future version of the item, but not vice versa. If you want to get rid of pesky enemies in the present, try getting rid of their source in the past.

2. Similarly, any pots broken in the past will be broken in the future. But the reverse is not true. You can break the same pot in the present, then one year ago, then 100 years ago; but it wouldn't work in the opposite order. Use this to earn some extra Kroniicoin or build an army of Otomos.

3. On the subject of Otomos, you may notice that they often do more harm than good. In the end, they are just trying their best, and will seek out and explode on any enemy that gets close to them. If you are too close, you might get hit as collateral, so be careful and keep your distance.

4. Travelling back in time causes you to meet an exact duplicate of yourself, including your items and Kroniicoin (minus the amount you spent to go back, of course). This means that your inventory will grow exponentially. It also means you probably don't want to spend 1000 Kroniicoin when you only have 1001 because then you'll be working your way up from the bottom again.

5. Tired of corpse runs to get your Kroniicoin back so you can travel back in time? Simply die in your room and don't loot the corpse. Unlooted corpses will remain until they are looted, so you can bank as much Kroniicoin as you want at the cost of lowering your wealth in the long run due to the lack of exponential growth. Just be aware that corpses follow the same causality as other objects, so a corpse that died in the present won't be there one year ago.
