The most recent update just came through. The list if changes includes: - fixed missing collision on level 4 - fixed Challenge Mode possibly quitting to menu after finishing just one level - updated font for Chinese - forced starting the game in windowed mode on Linux - added missing dates for the Special Time of Year achievement on Linux - allowed to use keyboard in the menu even if controller is select as the input device While the list of changes might not be impressive, it was a very much needed update. All of the improvements were made thanks to people who let us know about them - either by contacting us directly on Steam or Facebook, or by posting screenshots and starting forum threads. So thanks everyone, it was really great of you to let us know about these problems! It's worth noting that aside from fixing the above, we also spent some time on investigating other issues, such as the one where the Monster might go through locked door. Unfortunately we were unable to reproduce it on our end, which makes it tricky to fix. Everything appears to be set up correctly - collisions on the walls and the door are in place, the nav point on player character before the door are closed is there, and another nav point after the player locks the door behind them is triggered correctly as well. Therefore, everything that's required for the system to work is OK but apparently there must be some exception which causes the system to fail. However being unable to actually see the issue and debug it, makes it hard to pinpoint and fix. We also gave some thought to the way controller is handled on Linux. This works perfectly on Windows - if there's no controller connected, it is impossible to select controller as the input device, and if the controller is used and gets disabled at any point, the game then defaults to keyboard instead. On our Linux machine however, it is always possible to enable the controller, even if one isn't connected. The problematic part was that once player switched to controller input and had no controller connected, it was necessary to shut down the game as it wouldn't receive input from the keyboard anymore. Hopefully this is something we'll figure out for the next game. As always, thanks for playing the game and great feedback!
