Ah yeah, that's just where the game ends-- it's all I had time for ahaha.
I'll make it loop if I have time today. Thanks for playing all the way through :)
Edit: I fixed the bug! Now it loops at the end of level 2, so that you get a chance to see more rooms in both levels, and see how the game changes with different layouts.
Re-evaluation much appreciated if that bug was a factor in your assessment:)
