We're not very happy right now how Open Sewer currently plays and looks, so we will redesign the main level and split it into smaller more manageable zones with more detail and content.
There will be small patch to the current version fixing few bugs and improving FPS, before starting the redesign process. Then there'll be quite a delay before next update.
We pushed an update to Open Sewer, which unfortunately is uncompatible with saves from previous versions, therefore we added public branch of the game for 0.1.0, if you wish to keep your saves and continue playing on older version.
