Feedback and bugs
Something broke, felt wrong, or was good enough to say so. No account, and no email unless you want a reply. Every report is read by the person who makes the games, and what is being worked on is listed further down.
What has been reported
Reports that have been read and are being worked on, in the studio's words. What you write, your address and your run are never shown here.
Nothing on the list yet. The demo has only just gone up; the first reports will appear here once they have been read.
