Wow, this game wasn't at all what I thought it would be. As background context, I'm not a big fan of farming games or cozy games. It just isn't really my type of genre, so I held off on playing this game for quite a while because of it.
I won't go too much into critiques because I see almost everyone here already said them (enemy variety, grindiness, crashes). Most of them can be chalked up to "game jam time pressure". And I understand. So I'll focus a bit on concept and potential.
I'll start by saying... as someone who hates the farming game genre, this game actually got me more hooked then almost any farming game I've played.
In a way... I feel like this game almost feels like a subversion of the genre. Or a deconstruction of it. Maybe I'm reading too much into it. But the twist caught me completely off guard and I suddenly found myself way more engaged then I thought I would be. If anything this game shows just how important story is at changing motivations in a game.
Anyways, I think this may be just me but I actually found that the game changed from a Cozy game to actually quite a stressful game. But in a good way (for me). As in... I was really engaged. I was taking more risks trying to get every scrap of material and seed I could in order to make sure I could afford the modules every day. I was thinking about how to optimize my planting, and I was making tough decisions between buying upgrades and buying CC modules.
I do not know your design intentions, but I feel like I would enjoy a game that doubled down on this aspect of the game, as it really is kind of heartbreaking to see CC slowly degrade, and I think that emotional drive can be a powerful motivator. As you start to work tirelessly to prolong what could potentially be an inevitable end, I could imagine a lot of cool moments and great storytelling potential here.
You could work tirelessly to spend every last second trying to extend CC's life as long as possible, but in turn be barely able to see her? Or you could take it a bit more slowly and spend some moments just enjoying the time they have left?
You could make small interactions where things become harder and harder for CC, and maintenance tasks become more complicated and more demanding over time.
There is a lot of potential for some really powerful moments here! I think... if you guys decide to continue onward, I think the key to focus on (besides the other things people mentioned), would be presentation. There are some cool tricks you guys do (like muting the music for one chapter, and giving CC little animations) but more is always better. The writing and the concepts are already there, it's just up to presentation to give the story justice!
Good luck, this game is definitely one of the coolest ones this jam. I think it's really funny thought how both this game and my game have a somewhat similar base premise but the story is almost... reversed.
