Thank you for the response.
There was a lot I had in mind for some more thematic-fitting UI, but admittedly I ended up rushing the entire project due to working on another jam at the same time that this one was ongoing.
For the TV theme, it was intended to be as if you were watching a security cam of the ongoing room, and for the Trick-or-Treat mechanic (which I didn't actually write out anywhere else until just now), the helpful feature of time slowing can turn against you; enemies have a chance to spawn in quicksilvered and hasten instead of slowing down.
