I love this game so much!! :D

I can't see the collectibles or the plane in the first level

wait what i though it was ena the character

Great! I loved it! Very inspiring.

This game was a lot of fun! It is like playing in an ENA episode

I Loved the game! So beautiful and creative.I had a lot of fun playing it. 

Thanks for your work <3


Hi! I liked your game a lot. Ena-like artstyle, plenty of various looking characters, and the old MS DOS system, when pressing esc/launching somnium. 

But there is also one thing i would want to know about this game. how to access the folders in the recycle bin?????? I collected ALL letters, thinking it would do it. But it haven't. So how to access them?

(1 edit)

Hello! I loved your game. The feel of the game was incredible, and I liked the concept! I wish I found all the letters >.> I also recorded a video on my playthrough!


the king patting the Horse (I forgot if he has a name or not) is the best thing i have ever seen 



Out of all the characters, Ruka is my favorite


This is super fun! My favorite thing about this game is the graphics, there so cool! It wasn't very long but I find short games fun. If there's games like this I would play them! 


Fantastic game! It wasn't very long (30 mins), but it didn't need to be. Every mini-scenario lasted just the right length of time. The tone and appearance of the game are also absolutely on point. I can clearly see the Ena influence, which is why I tried it in the first place. If the developer makes more, I'll certainly be first in line to play that, too.


Same! I'd enjoy playing a game that either continued this story or is, just, in any way similar to the original story of Somnium.


overall a really cool game. was really fun and left me with many questions. you can tell the creators genuinely knew what they were doing. wasnt too long too meaning it didnt require much commitment. really enjoyed it :)


linux version of the game wasn't rendering correctly; hoping for a fix so I can try this game out

very stunning game. also i think i found the easter egg. i don't want to spoiler things to those who haven't played the game yet, but in the somnium os, click the recycle icon, you'll notice a file called "freewifi.cmd". it will respond with "hold up". same thing with opening cmd and typing "freewifi".

edit: also, if you typed help 2, and scroll down a little bit you'll see a message called "secret: GET WIFI ANYWHERE YOU GO (freewifi)"

yet another easter egg; type in "help cheats". this will give you a list of cheats inside the game (not recommended for first experience)

i think the devs were referring to this one cursed meme that the gen z has taken over lol. great game tho!


Without a doubt an amazing game. It has a very strong nostalgic flavor, plus a simple but functional gameplay and a relaxing soundtrack. It's just a shame it's so short.

Anyway, an excellent game. Congratulations.


i agree. it kinda gives you this early 80s vibe wich i like it


how to play ena cuz on youtube people have been "speedrunning" ena and making skips. here are two examples:

(2) ENA - Temptation Stairway SPEEDRUN WORLD RECORD [any%] - giberic on youtube

(2) ENA - Temptation Stairway Any% speedrun - 1:44.61 (WORLD RECORD) - Kraizelle on youtube

anyways pretty weird but giberic made an video on how to install it but never mentioned how to play 

on temptation stairway

need help!

wow, 10/10 the fact that you need to complete task for one email is a adventure. its such a wonderful riddle game. . ive completed it and wow its a very fun game, would recommend for those puzzle people who wanna shape there brain. -reemo

I love so much this game,it's pretty good :D




this is why youtube exist


did you said... TURRÓN?


i love this game, even tho it was just about a email, i still love it

This game is one of my favorites now, oh and I also came from the ENA animations by Joel G. Salutations fellow ENA fans! Anyways, I have played several endings, one with cheats on and one with everything completed

If you want to know where to get the cheats look below me, I see there is one explaining it in the comments down there. A really nice community I might say.

I finished the game on my old Mac that I fixed a couple years ago. (it was my moms haha) This game just stands out due to the aesthetic and concept. It's like a different ENA episode starring side characters of the said universe I love it so much. I also enjoy the replay-ability and simplistic yet wacky style. I'd rate it 100/10.   

I'm a new itch.io user hello. :)


could you tell us the cheats or who commented them i cant find it :(((

i loved this game sm ahhh omg i absolutely love ena and playing this game really filled that void i felt from the lack of ena and ena universe content I've been receiving lmao

Well it was fun trying to play it but I can't play it.  X, c I still had fun painting with the cursor


this game is amazing, i would rate it a 10/10, i just finished it and i enjoyed every second, would highly recommend this game to my friends and that's just the beginning, i have so much more to say about this game, but i'll just say one thing, the graphics are amazing, i always love ps1 styled games, i just can't put how much i enjoyed this game into words 

(1 edit)

this is so perfect,i just finished, i want so much more, i'm in love with it. if theres anyone interested but doesnt know if its worth it, just install rn, you wont regret it, tysm for the creator, im so in love


Personally, one of my favorite games on Itch.io so far! And yes, I came from ENA.

Much love to the devs of the game! <3

I love it, it's very cute; It's a great game based on ena. I love its retro and pixelated style and how well it runs, it really is very good. Tks for this game <3


I love this game, but I only got to play it once. For some reason the start button stopped working :(


a wonderful game, i just finished playing it and will certainly play again a lot of times. The graphics and colors are really pretty and the characters are amazing.


this looks like a drug trip

because it is, its basically lsd simulator


very nice game

praise to the devs 

Don't know if this is a glitch or if I am being a dumbass with the CMD, but I honest to God can't get Page 2 of Help. I tried typing it in different ways and it always gets me to Page 1.    

Great game, anyway. Would the devs consider uploading the (excellent) OST to Youtube? 


The soundtrack has been uploaded to YouTube as well as on this page if you would like to download it.

Regarding the help command: In order to view the other pages do "help 2" without the quotes. Perhaps you were including the # sign which it seems the console doesn't recognize.

jokes on you somnium team, i have found the cheats command


pls explain me how


this game is a turron moment

thanks for coming to my ted talk

This is a really good game man! 

It looks like a ENA game, But good (:

did it bother you
