Thank you for the kind words!
About room changes: we also had the same feeling when we were playtesting D: Adding transitions/animations ended up being the top item in our leftover polish list. We figured out how to use effects only too late in the jam process, and we ended up calling it a day.
It was our first time using HyperCard, so everything was new and unknown.
I’m considering doing a post-jam update to tweak many of these small things, though, so thanks for the feedback :D
