Well the game is a good one because it does the scares very well esp for a short game! But it seems like i got trolled by the dev? i think? It's because of the second ending that everyone can't seem to get, which seemed like cleaning the last stain that was next to the monster spawn (after he spawns) and get to the elevator. After an hour or total play time, i was able to clean the appearing stain and make it out alive, but still got ending one (if you look at a stain and hold down the clean button even if running the stain will get cleaned).
If the second ending being impossible to get is intentional, than i like that (although frustrating) because i've always liked trollface stuff. Either way the dev made this game stick in my memory so he was smart to do that so GG dev :))
