On a non-Ubuntu system (Gentoo) I was able to replicate this by doing the following:

Grab the file libstdc++6_7.2.0-1ubuntu1-16.04_amd64.deb from the repo manually.
https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test/+files/libstdc++6...

Extract the deb by using deb2targz (or you can use the ar command)

Move the freshly extracted file ./usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.24 to your deceiver directory

ln -s libstdc++.so.6.0.24 libstdc++.so.6

Execute the game by typing the following in the deceiver directory

LD_LIBRARY_PATH=. ./deceiver

Edit: Game launches, but gives a message about requiring the itch app.

Since we have to use the itch app, we should do the above in the itch dir for the game:

~username/.config/itch/apps/Deceiver/

Put the libstdc++.so.6 symlink in that dir
Move the deceiver binary to deceiver.bin (or something)
mv deceiver deceiver.bin

Now make a shell script to set up the LD stuff and name it deceiver, and chmod it 755

#!/bin/bash

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:. ./deceiver.bin

If you can make a linux build for this, I'd buy and test :)

I'm eager to hear an update regarding linux support for this title :)
I'm a backer.

Any thoughts on making a linux version?

Does it have a linux build?

No worries. I can play around with it whenever you get to it :)

Neat! Okay, I've bought the game and am eager to give a test build a test :)

Looks like a neat game, can you post a linux test build? :)

This game is amazing so far and I can't wait to be able to play it with my buddies on the couch on SteamOS :)

Neat, well it appears to work well under Linux. Gentoo, 64bit, nvidia. There are some oddities but I haven't been able to reproduce them reliably yet.

Where do you want bugs reported? :)

Looks neat! Does it have a linux build?

I really enjoyed this game. Since it is free, everyone should give it a shot.

I'd definitely buy an expanded version :) (Thanks for the linux support!)
