I am here to review your game, whatever I played of it that is. I have no video sadly, but I did my best to screenshot what was important (I missed one though).
First off, I really like managment/tycoon sims, so this would click with me well. Reminded me of the VN style VTuber Agency sims I played in the past.
First issue I encountered with the game was a forced fullscreen which led to a "Unsupported Size" error on my moniter, which in my experience is a big pain to fix because as long as the program is running I can't see. Thankfully the game fixed itself but still ran at 1080, which I thought was cool you had that failsafe implemented. My resolution wasn't there in settings, but I do have a weird Aspect Ratio (I forgot it), but for reference I have/use a 1440x900p moniter. Setting resolution lower usually helped me in other games, but I tried in this game and it just blurs everything, so I left it at 1080 (esspecially since it works anyway).
I was a little confused when Enter was not an input for continuing text, like most VN's. But I do later learn it is used as the skip button later on, so it made sense to reserve it for special things like that.
Now, I did have issues with the Animated Scene. It was super cool to have, but I had the major issue of not being able to read (sometimes not fast enough) and see all there is to see in the visuals. Now I do watch subbed anime, so I'm not a noob at speedreading dialog, but I do sometimes rewind 10 seconds so I can see what I misread, or just see the visuals in full without reading. So for this animated scene, I was disappointed in myself for missing out. And I did think it was an animated scene which would allow me to control the text, like the ones where the scene will loop until I finish reading and let it continue with the rest, if you understand what I mean. Because this was super cool to have, but I missed out on some of it because of the text, which I also will complain, what felt like small white text with all the flashy visuals, was hard to read.
When needing to pick my Date of Birth, I had an issue of confusion. Was it Year, Month, Day? Day, Month, Year? For reference I grew up and always used the Month/Day/Year format, but I knew the other one existed. So this confused me for a few minutes until I figured out it was Day/Month/Year, when my first thought was Year/Month/Day. And this is a very minor confusion, but was I setting my age, or setting the year? 1921? Or I'm 21? lol
Minor nit-pick, but if the game takes place in Korea, I would have liked the game to have used Korean dollars(Won) ₩, extra points if the game is priced around Won and Korean prices. Instead it used $$ which made it feel very American for me, lol. Makes it feel like a game made for foreigners, or a foreigner made a game for foreigner (his/her country), if that makes sense. Could be a setting, could not. Ultimattly I'm fine either way, but I wanted to list this thought. It's just something small which would make it feel more closer like I, myself, am in Korea.
Major bug when editing the contract, was it would auto-confirm everytime. And when it doesn't, I can't click my group name, because it would reselect Youth, also when my mouse hovers over a concept it auto-selects which then auto-confirms.
I wish I did take a screenshot of it but had a visual bug where normal UI Controls were being shown, but now on top of the new Controls shown for the current UI that opened. My apoligies for not getting a screenshot on that.
I did read that you could audition on top of the schedule, but did not know it didn't auto-deselect it (I didn't want to do it again, and thought I'd need to manually add autitioning every week), I am unsure if it used up money.
Last issue I had, was the "interview" was always greyed out, so I didn't click it. Then when I tried, and saw it was just artistic choice to grey it out, I regreted never clicking it on my first auditions. Missed out on lore.
The reason I stopped playing the demo was this:
And then I was stuck, unable to select anything but a single invisible button on the window which did nothing. After being stuck I just saved and left the game to leave my review.
Now I did just list a lot of negative things, I did have fun with what I did experience, the Rythm Mini-Game was fun and quite easiy, the audition mini-game not so much in easiness, I did get 4 perfects but my 2nd one I was unprepared for the reasons I listed. Game is my cup of tea, and I did wishlist it for later.
I hope you find this useful, and good luck on game making!
