If I upload the main file, the playdate sideloading interface says there isn't a top-level .pdx file. If I upload the .pdx folder (?), it says wrong filetype. Am I missing something?

Oquonie is a textless adventure across an intertwined megastructure. · By
UPDATE - I got it working, the problem was the zip file contained the file structure Oquonie/Oquonie.pdx/<all the subfolders & files>, but the playdate website expects the Oquonie.pdx to be the root folder inside that zip file (i.e, just Oquonie.pdx/<all the subfolders & files>). Once I zipped up the Oquonie.pdx folder by itself the upload worked no problem
But it does, it's just that you must be on a different operating system than us. Like we said in the thread, linux compiled files behave a bit different than on Mac, but the file can be made to work by unzipping and re-zipping it with your system.
We don't have access to apple devices to make a OSX compatible zip file.
We already began the refund process with itch.io, it'll get sent back to you via your payment method. We're not certain what that's going to look like on your end, but we'll keep you updated. You have nothing to do on your end for the moment. It should get processed very soon. Thanks for your patience.
We just got a message from itch.io saying that they processed the refund, they told us that it should be reflected on your method of payment within a few business days(i see it now listed as refunded as well on our end). Sorry it took so long, they process each request by hand so it takes a while (any action like this on itch.io takes forever...).
Cheers!
