Hello. Thanks for playing! Yeah unfortunately in this version the second level is bugged... Its been fixed since then and we will upload a significantly improved and updated version after the end of the game jam.
Regarding the bug with the end screen appearing unexpectedly. You are the second person who managed to trigger this issue - or at least the second who reported it, and we weren't able to reproduce it so far. Do you by any chance remember what you did before it happened?
