Okay, so let's start with the positive side here: "we have a bunch of stock sprites provided for the jam, what if we took them all, created characters for them, and stuck them all in a game show" is a really fun idea.
It's an ambitious plan that has, up to this point, unfortunately not stuck the landing.
This review is going to be fairly critical, but please don't take it personally. All of this is meant to be constructive, and I wouldn't be taking the time to write this out if I didn't want to see you improve.
Walking through each of the categories, with spoilers from this point out:
Implementation of Theme:
Well... there was an attempt, clearly, with the VN and in-universe game show being called "Find Your Light", but the theme wasn't just "light", it was "a light in the darkness". I'm having trouble spotting what exactly the "darkness" is for the MC or really anyone else in this story, other than just like, being single. Everybody seems mostly fine here; the biggest struggle any of the characters show is being kinda shy. Compared to some of the directions other jam submissions have gone with the themes, this is on the weaker end.
Story:
I'm not gonna sugar coat it here, there are myriad problems with the story so far.
1) The MC: Pretty much all of the cast so far have paper thin personalities, but the MC's is practically nonexistent. While I generally dislike "blank slate" protagonists, I can understand the need for it in this kind of situation where the MC is supposed to be the player's avatar, as if the player was the one actually participating in the game show. However, if you're going to go in that direction the player needs to have some actual agency in choosing how to handle certain interactions and choosing who to spend time with. If you're not going to have this level of choice and interaction, that's fine, but then you also need to develop the MC's personality. There are several points at the dinner/dance scene where characters remark about how the MC does his own thing, but how would they know that? He's spoken like five times up until that point and none of those have been anything of substance.
2) Narrative efficiency: This goes a little bit towards characterizing the MC as well, but let's look at some numbers here: there are 1276 lines in the "script" file and 230 in the Christian route file. In the former, between Ethan's introduction and the "choice" (quotes because they all lead to the same place) of who to spend time with during the first event there are approximately 600 consecutive lines where the MC is not mentioned in either speech or action. Of the 230 in the latter, about 60 of those are describing other couples getting together. Close to a full half of your story that is ostensibly about the player's character participating in a game show consists of spectating secondary, presumably non-romanceable contestants. That is... not great. Besides the fact that the focus is in the wrong place, there's a lot of repetition too. You don't need every character to be surprised that the tarantula is a good dancer. I got it the first time.
3) Setting: There are a few aspects of the game show itself that either don't make sense or aren't clearly explained. When the MC arrives at the house, the other characters welcome him to "the group" as if they've been there for a while and are already familiar with each other, with some of them talking like they've been there before. At the end of the first event, Ethan also talks like this, saying "I've seen how others react when they first arrive". Does he mean from watching the show on TV? Or is he a repeat contestant? Otherwise how would he have seen that? He just got there too and was the second to last to arrive. There's also a lack of clarity in what is actually being filmed as part of the broadcast and what isn't. It would be helpful to indicate when the MC is on camera and not. There's a lot you could play with regarding characters behaving different when on camera (either of their own volition or at the behest of producers) but none of that is coming through.
4) Christian: This one might be a matter of personal preference, but that super pushy attitude raises a lot of red flags for me and I felt very uncomfortable interacting with him.
Presentation:
It was mostly fine. I'm not going to knock you on the stock sprites obviously. There wasn't anything wrong with the presentation per se (even if the music got a bit repetitive after a while), but it didn't do much to stand out either.
Creativity:
As stated at the top, I think the premise here is a good idea. Throwing everyone into a game show and letting the player sort it out is a fun approach. Ultimately though, I think a lot of the decisions from that point needed some more time in the oven before this was ready to go.
Again, this is all meant to be constructive - I hope you stick with writing and game design, whether it's continuing with this project or trying again with something new. While this might have stumbled in some areas, I hope you can take the criticism as a learning experience as you go on to create bigger and better things.
