Hello. We're sorry to hear about the download error. Could you clarify if this only happened on itch.io? This is assuming that you have downloaded other 1GB content or similar file sizes. Perhaps try refreshing it? There's also the possibility that the files were missing during the download process which can happen due to the large file size. We hope to help you resolve this as much as we could. Thank you for your interest in the game and have a nice day.
