This game was really good! Going in knowing it was a horror game left me with a strong sense of paranoia and tension playing through, worrying about what would happen if I got caught trying to sneak out or having been caught losing the brush. Unfortunately because of this I rushed through and forgot to explore around and find all the key items, and had to redo it to get the hidden ending ^^; The hidden ending was very eerie though- I found it very interesting that all of the stages in the tower are somewhat claustrophobic but otherwise safe, but once you get underground and the space opens up and the screen scrolls, that's where you find the actual horror.
I was a bit confused by the ending, however, and what all of the strange things happening down there were. It was definitely very creepy and I had the definite sense that I was seeing something I wasn't supposed to see, but it was hard to tell exactly what it was. In some ways that added to the sense of horror, but in other ways it made the very end feel more confusing because I wasn't sure WHY Lavender's mother had to *spoilers*.
The art for this game was really good though- I loved how simple it was. It made the sprites really beautiful, and very cute. Did you make all of the art yourself? It was a really fun experience, and I'm glad that I played it!
