Fixed potential startup issue with builds

UPDATE 21/29/21

In the latest builds I fixed a bug where it was possible to get stuck on the starting island and related issues with level transitions to other parts of the island

Development Notes:
This is my entry for LSD Jam 21. Inspired by the atmosphere of LSD Dream Emulator as well as trips taken around California and the western U.S. The writing in the game is generated randomly, written via a cut-up technique or transcribed directly from dreams to the best of my ability.

I may update this project with new content/fixes. Due to time and other constraints there's a lot I didn't get to include, particularly a number of scripted dream sequences. Instead I focused on building distinct areas for the island. In the future I'd like to create a tighter, more narratively focused experience using some of these assets or concepts. I had a lot of fun making it and following the progress of other developers, I hope you enjoy.

Thanks! Yeah send me an email: jacob.potterfield@gmail.com. Loved your game Somewhere by the way, excellent work


You guys go and create something amazing again! Together it will be amazinger!!!

(1 edit)

Somehow it's very laggy, while having PS1 graphics. UI is rather bad.


why can't we claim this?

Interesting vibe and atmosphere, great work!

Dude I'm seeing s__t...

I will take this game for free in my website if you give me the code for that

from distribute section

This has to be one of the best games i've ever played on Itch.io, the city, the feeling, it feels like being on a dream... it's just amazing... thank you for this!

That's nice to hear I'm glad you enjoyed it. Thanks for checking it out!

A bug that I noticed:

Sometimes after talking to someone/interacting with something/warping, the camera rotation angle get limited, preventing you from facing certain directions.

Never noticed that before, I'll look into it thanks!


I can't start it. it says that "DreamIsland CreateProcess() returns 2"

Not sure what was going on there but if you re-download the latest build it should be fixed. Let me know if your still having the issue.

So, now it starts, but my computer is not very strong. so it lags a lot (also got a problem when the sound of a car screeching to a halt kept going unless I stopped playing)

Should I try with the 32 bit version if it runs better?

I don't think the 32 bit version would make a huge difference. It requires a fairly modern graphics card to run well. I didn't spend much time on optimization given the scope of the Jam.
