not bad
I struggled with the vent scene too, at first I thought that there was no way out of the vent, but then success(didn't seem to be that great of a reward other than telling you that you escaped, maybe an applause or cheering sound could've made your point that HEY, you ESCAPED!)....I gave you a "7" cause it seems like you put a lot of effort into the interaction, giving the viewers lots of choices, though personally I don't really like the whole idea about interaction on an elementary school (1st grade).
