First of all, the art is superb! I really like the music (lavender town vibes) and story as well, both sad and incredibly sweet.
It's nicely polished game, just needs some more varieties of enemies mainly, I think. It would be nice if there were more levels as well.
It would be cool if each baby cat was more unique as well, in both look and what they offer. So like, one cat maybe fat and eats fish immediately if you give to them, but they give extra ammo if you give them bullets. Something along those lines.
Hunger doesn't seem to do much, as far as I can tell.
I also think it's a little confusing that you grab stuff with with the mouse cursor, and not the ghost mama herself. Because the mouse cursor is used to aim the gun, so my brain didn't think it could also grab stuff. Maybe if you had a custom, in-game cursor, like a paw, that wouldn't be an issue.
Maybe that's just me though. I don't know.
Overall, really enjoyed it! Love the level of polish you put in, even adding in a tutorial at the start. Which is rare in a game jam!
Hope to see you in more game jams! :D
