Speaking in this this official US PLayStation blog post, Echochrome producer Kumi Yuasa has promised that user-created puzzles will be available to download for the puzzler, for free, on a regular basis. From Eurogamer:
The developers will hand-pick each batch, and they will be playable for as long as it takes the team to select and release a subsequent compilation.
To have your creation included, simply select “Canvas” from the main menu and tinker until you can play and complete your puzzle.
Once finished, pop to the portfolio menu and either “send” it to a friend or “upload” it to the developers. In the PSP version you can only “send” your levels Ad Hoc to friends.
More through the link. No release date for the Escher-inspired oddity as yet, but we’re hoping to hear something on a European release from the SCEE PlayStation Day in London later today.
