Hi! Gave it a try, here are my honest first impressions. Just so you know, I'm probably not the target player for this kind of game, so take this with that in mind.
Overall, the art is really nice and the sound design too, it all feels cozy and well put together.
1. After the first minute, I understood the basic loop: you give items to the creatures, they change, and you can sell them. It felt like a collection game, a bit like a Tamagotchi, but I didn't see the bigger goal behind it.
2. Where I got confused: why one item rather than another, and what selling a creature brings me. A clearer link between what I give, what the creature becomes and what I get from it would give a reason to experiment but maybe it s done on purpose
3. Would I come back tomorrow? Not yet, mostly because I didn't see what I was working towards. With a clearer goal, the cozy jar idea could definitely make me come back to check on them.
The concept is cute, I think it just needs a clearer "why". Good luck with it!
