It's known issue. In fact the game was prepared for Wapniak 2016 party but due to some mysterious circumctances it hasn't been finished enough to show it publicly.
This year guys put the stuff together and released the game. Unfortunately, it's still party version, and some things are missing, and there are some issues as well. So - stay tuned and wait for the final version.
It's a pretty obvious problem, but I wanted to report it since this is coming from PAL land and maybe only an NTSC issue.
