hi. Thanks for the help. Also, to avoid that issue, we could just use screen curtain.

hi. I played this on my pc and loved it! However, i wish to play it on my iphone. However, when i keep the app open the phone locks itself after a few minutes. Could you help?

Hey there, To fix this, go to settings, then Display and Brightness, and find the option called Auto Lock.

Select that and then change the setting to never.

This is less secure though, since if you do not always manually lock your phone with the side button, someone could get into it easily if you left it unlocked. But you could always change the setting back when done using the app for the day.

I'm totally blind, what are the controls, is fast forward accessible with the keyboard? Also, on the iOS version at the end, I don't know how you either start again or exit. It just ends, do I just restart the app? What's the situation with the PC version?

I can't seem to open the Kat Keene file on my Mac. Any help?

tons of fun! I've been wanting to play this since I saw the physical one at Indiecade, and looked again yesterday to discover that this port exists! Yay!

So glad you liked it!

Really like this game <3

Would love for a way to speed up trying different options on later plays

Thanks so much for the kind words, and thank you for the suggestion! I think this is a good idea, and I'll discuss it with the team. We're currently working on an update for this summer, and we probably won't have time to add in this feature, but we might be able to add it later on. :)

Just to let you know, we released an update last weekend that adds a fast-forward button to the game. You will need to download the file again in order to play the latest version.

This is great!

Such an intreeging short game

Thanks! I'm glad you were intrigued!


I did literally every wrong thing possible before breaking the curse.

Wow! What a great idea to put the Klaxo Radio into a game! I didn't manage to solve the radio's curse but I had fun!
