Played the demo and had a blast! Teresa was such a fun mc to play as and there was a nice balance of humor and tension. The first time I played, I got the bad end towards the end of the demo and had to rewind to pick another choice to not get offed. The villains aren't playing around and I hope to see this be maintained even as they start to fall in love with Teresa. (Good luck girl!)
Minor spoilers(?) for the questions
1. I'd probably pick Vicenzo as my first route since he seems to be more reasonable than Edel and already looks to have a bit of a soft spot for her. Edel is fun to interact with but I'll need to see more of him to want to go for his route.
2. My favorite scenes were the ones with her friends and brother. The mutual teasing and "I've got your back" is great to see, especially when I dislike seeing the og heroine as a scheming manipulator or a doormat to let the villainess shine. Also the accurate sibling representation. <3
3. They are villainous enough for me. I thought they had the right amount of charisma and in the grey for me to not be turned off. Plus their voices are nice.
4. This is fun speculation but I was looking through the faq and noticed that the answer for whether we'd get more love interests was rather... vague. So I started thinking of who would fit the criteria, and Teresa mentioned that that there were 4 ros in the og game. So far, we've seen three in the demo: the prince (confirmed non-romancable), our brother (nope), and Henry is already taken. So that leaves the fourth ro who has not appeared yet. With current knowledge he'd be my bet if another route is added.
