Played the whole thing, really fun and polished, not too difficult either. For some reason the download version didn't work, only the browser version. This is on Windows 10, and other Godot games have worked fine. Also, how do I get the last floor? Replayed the whole game after finishing the first time, hugged every wall, didn't find anything new. Kept an eye out for more of those invisible floors in case but nothing there either.
