I played this because I really liked your use of the Kenny asset pack in OOPS: Octopus Only Postal Service, which was the most creative design I saw in MizJam1.
You used many of the assets from the same pack, but in a very different way. Great job!
It's quite an ambitious story for such a simple setup but it delivers very well for a Jam Gam.
I enjoyed "Winter" as a character; really sold it as the personal story it seems to be from your Info section. Depression is a personal experience and telling the story as such fits well.
Nice job matching the audio to the mood after the club scene. The choice at the end isn't 100% clear you even have a choice; which is exactly how anxiety and depression presents itself for a lot of people.
It might enhance the atmosphere by using dynamic post-processing throughout to color-shift the game to be more muted when Zel's mood is low, and apply a faint vignette to create a sense of claustrophobia when she's feeling trapped.
If this is new to you and you want a link to a tutorial on how to implement these let me know, I couldn't find a Brackeys one that isn't out of date. The video below though does include what they can do.
Great job overall! Looking forward to your next game.
