I enjoyed this game and I liked the concept overall! I liked how the game looked and the general feel of it!
If you are thinking of adding something post-jam, I think right now you can kinda set yourself up to endlessly defeat enemies easily. Maybe something that could be interesting to explore is a timer of some kind. That way, there might be situations where there's incentive to increase fear so you can get a higher score within a time limit. You could even add little time power ups that drop around the room that add to your time (or freeze it, or something like that) so you have more incentive to move around. Alternatively, making the enemies more difficult over time might work well too (I wasn't sure if this was already a thing in the game or not, if it is, my bad for not noticing!). These suggestions are pretty subjective, so whatever works best; I already had fun with the game as is!
Great job on the game!
