i wish there were more games like this. Very good game!!

i enjoy it a lot i give me heavy ENA vibes although i wish there is more to it :

Hey! I loved this game, but I noticed that there's a few songs in the OST that aren't in the game. I also noticed that there's a cheat thing in the terminal but I can't find any usable commands, which leads me to ask: Are there any secrets about the game I might be missing?


such a fun game :D 

Man, this was such a good experience! I would love to play more games like this :3

Played this game. I want to bite it and wring it around in my mouth (Positively)

This was actually fun! I love the graphics! It looks like Windows 98! A true classic!


Hello there, I really love this game it was nice but i have a few problems which i found out after seeing someone play the game online. i didnt know it was a problem, the letters and planes were missing for me and a ew other main elements in the map too. i played from mac and still do. i tried reinstalling it a couple times but its still the issue, they're not visible :') i hope this bugs can be fixed cause i or any other mac players wont be able to proceed with the game


Sorry you are having those issues. If you haven't already try enabling the "Disable Advanced Shader", this does change the way those objects are shown but at least they are visible.

If you are fine answering it on this forum publicly: What version of macOS are you using and what particular model of mac are you playing on?

No Problem! I will try enabling the "Disable Advance Shader" Option.  The version of my macOS is 12.3.1 and the name of the model is Macbook Air (13-inch, Early 2015) Apologies for the Very Late Reply, I'm still working on how to use the site's tiny features like this notification pop-up


Hello There! As per your advice, I tried enabling the "Disable Advanced Shader" They were Visible!
Thank you so much for your help! The entire Game Play was immersive and very Utopian! Loved the Game!

Very nice game and a cool tribute to ENA!

A very cute experience. Put a smile on my face. Creative!


I loved this game's style homage to the ENA series and it's short/sweet length in gameplay.


i cant play the game, whenever i try to play it,it just says that it cant find the code or something and reinstallng may help.But whenever i re-install it, it still wouldnt work.

love this game


I really loved the game! I even recorded my own playthrough of it. Now I would highly suggest to first play the game yourself before watching others!
Idk if I should link it, but since others did it, I might as well 

this was, enjoyable

this is the best thing i have ever experienced 

i love thisss!!

it's very very fun, I played in cool rooms and the characters are very coo

How do i play this

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
