I purchased this as part of a bundle and don't seem to have received a Steam key. Am I still eligible to receive one? I'm playing on Linux and am having separate problems with both the Linux release and WINEing the Windows version that would be solved by using Steam.


Hi, the bundle is supposed to be for the DRM free version, not Steam. But I'll make an exception, send me an email at contact@cowcatgames.com

Thank you so much! Having lots of fun so far.

Where can I buy version 1.5 ?

I'm not aware of such version :p If you mean the latest version on Steam, there's not much difference aside from chapter select.

Only this version runs on my computer!

Hmm my version naming for the demo must have been different from the full game. That demo must be old.

EDIT: Yep I checked, that demo is 5 years old.

The current version on itch.io (1.2.1) is the latest one, same on Steam. Do you have an old computer that can't run 64 bit?

EDIT 2: I have retrieved an older 1.0.6 version for Linux which should be more or less the same one as that demo and works with 32 bit Linux. I've uploaded it here.

I can not buy games here.

I bought the game on GOG.

Can you make this version available on GOG as well?


Sorry, I can only put one version available on GOG, and I'm not going to put an early build. If you want an itch.io key to access the download I can give you one.

Just reach me to contact@cowcatgames.com

Got it in a bundle and finally got around to playing it. Had a lot of fun, really funny! Thanks for including a setting to disable one specific type of humour and ways to skip puzzles/get hints when needed; very useful. 

Good to hear!

Hello and congratulations :)
I haven't played the game yet, but may I ask why the name Demetrios?
Does the plot have something to do with the greek civilization?

Also available on IOS  

Very nice little Game (played it for 10 Hours on my Phone )

Thanks for playing!

I just bought the game and zero problems getting the Steam key :)

I love that it can be played on any platform :D

Glad to hear!

Hi!I can't find the Steam key.


Hi, some people are redeeming Steam keys so there must be a way - admittedly I'm not sure how myself considering itch.io doesn't consider I own the game. Maybe ask them? Worst case I could send you a key manually.

If you could send me a key i would be grateful.


Reach me at contact@cowcatgames.com :)

Hey, your Steam link goes to Fran Bow!


Woah, that's weird O_o

Anyway, it's fixed. Thanks!


Today I've updated Demetrios on Steam and other DRM Free builds for 64 bits (Mac and Linux) The Mac version is now a .dmg for easier install.

No change required on Windows! (which explains the version difference)

I'm trying to open it on my Mac and nothing's happening :/ I also tried going into package contents and opening the executable file directly but that didn't do anything either. Am I doing something wrong?

EDIT: running the executable file indicates this file is missing: 

Application Support/com.cowcatgames.demetrios/game.ios



I haven't updated the files since almost 2 years (but maybe no one tried the Mac version?) For some reason itch.io won't let me download my own game XD So I can't check.

But can you re-download it and check the content of the package? That file should be there. I've checked my latest package and the file was inside.

Of course if you're running the executable directly without extracting everything, it won't work. If I remember correctly, normally you simply have to double click on the downloaded file and it should install. (but admettedly, I rarely use a Mac and my memories from two years ago are fuzzy)

Worst case scenario, you can get a Steam key, for which the Mac version definitely works.

Yeah this was all after I extracted the ZIP download.  I only tried running the executable directly after the original file wouldn't work. I tried redownloading a few times and I keep getting the same error.

Let me know if I can get a Steam key instead!


That's weird, maybe the latest Mac OS updates broke something. You checked that you allowed "unknown sources files" in your OS settings? (can't remember how it's called exactly)

You should be able to get a Steam key with your itch.io purchase! Can't you?

Yeah,  I went on settings and allowed the file to run despite being from an unknown developer. It still wouldn't load.

Oh my bad I didn't know you can get a key from itch.io. I'll go do that now, thanks!


Hey, you know who's awesome? You are!

Well, thanks! :p


thank you! also thanks for such a great game,  I good lost in it all day today :)


Thanks! ^^

I've been working for 2 years on a new, very ambitious adventure game, I'm doing dev streams every day if you want to take a look : https://www.twitch.tv/cowcatgames

do you have a working demo?


Most of the game has been programmed and most dialog written (and it's a huge game!) but with 90% of placeholders for art/music. Currently trying to make it so we can play from start to end.

No public demo yet (because of the placeholders art) but if you're interested to be a beta tester, I'll probably start looking for some in 6 months so be sure to check me on Twitter where I post my news : https://twitter.com/COWCATGames

Hi Fabrice would I be able to become a beta tester for Brok!

where are the save games located? im on linux mint, thanks!


Hmm, I believe it should be in a /.config/Demetrios directory inside your /home directory. At least according to GamMaker'sdocumentation : https://docs.yoyogames.com/source/dadiospice/002_reference/file%20handling/file%...


I'm not a big fan of P&C but after playing around with the demo I had to buy it, this is fantastic, no issue with it running on Linux mint as well.  Thank you so much for a wonderful game.

Forgot to link to my full review of this highly enjoyable game:


Albeit I didn't have the opportunity to the play the version with the less pleasant bits taken out (didn't enjoy the toilet humour!)

Thanks and there's always time to replay the game with that option!


Finished it now after 10 hours and am quite satisfied :-D It's very polished (I have encountered no bugs or crashes), the story is entertaining, the puzzles not to hard, there are some nice minigames - one can see that there was much love put into this game. Only the jokes/the dialogues got a bit enervating over the time, especially towards the end it became very disgusting - too much pissing, pooping, farting and vomiting ;-)

But besides that it was fun and kept me interested the whole time :D


Thank you! :)

About toilet humor, that's why there's a choice to filter it when starting the game ;)


Finally, I get to review this!

I'm not too big on point-and-clickers, but this game's the rare exception. It reminds me of old school P&C games in its presentation and execution.

Graphically, everything's bright and colorful. The soundtrack's easy on the ears, although it can get a bit repetitive after a while. Controls... well, it's a point-and-click game.

There's really not much I can say here that hasn't been said in the video. Very nice game!

Thank you very much for the video review :) I'm glad you liked it!
