Thanks for the feedback!
I'm still investigating the issue that causes the crash, the frequency it happens seems to vary from player to player and it's rather difficult to track down as it only happens in release builds. The save and load system was pretty rushed so I'm assuming it might be related to that. This is the first report of a crash when reaching the end screen though, I'll look further into it.
I'll take what you said into consideration. There was actually some sort of radar mechanic that was originally planned to be in the game that would let you see the whole room for a moment, but I thought it felt somewhat off in relation to the gameplay overall; I couldn't figure out an interesting way to limit its use and make it more meaningful back then and I was running out of time, so it got cut. I might definitely rethink it in case I keep on expanding the game.
