Bugs I found:
No way to unpause without choosing an option
If you pause while in the bottom view you have to restart or quit (can't go to a checkpoint)
Sometimes "F" wouldn't swap views
Timer was broken and I got multiple overlaid times
General gameplay notes:
Going up stairs was slow and frustrating
I really liked the contrast between the two viewpoint's atmospheres!
Overall review:
There didn't seem to be so much of a game here as much as a proof of concept, but I could definitely see some puzzle elements that you could build upon later. The quotes and set pieces hinted to a bigger picture which was cool. I liked the music, atmosphere, and dual-viewpoint stuff! Just wish there was more to do and that you had more time to expand on this theme.
