Got a 6:30 time on my first timer mode attempt (mapless :))
Really fun, short little horror game. I love the art style, the cute character contrasts with otherwise quite gross and creepy environment nicely. There's quite a bit of personality packed into this small game, even just in the loading screen and menu.
The presence of the monster provided tension, however I almost felt too safe since you're only in danger in the hall and there's not many spots where you can't just dip into a room/shortcut. It's mostly just a nuisance (especially in the timer mode).
5/5 for a short free game.
