Fun game! Took me a moment to figure out the left click thing due to my language limitations but I did! I'm not sure if I was meant to be but I think at the end after the last level I spammed the Space bar to get to the 'next' level and I spawned outside a building with lots of rooms and enemies that gives off test level vibes - had a different/grey background to the other levels otherwise I'd have assumed it was just another level
