I LOVE THIS GAMEEEEEEEEEEEEE!!!!!!!!! This is so good!!!!! Omg it's literally perfect for me I adore animal-based foraging survival games and jerboas are one of my favourite animal how did you know!!!!!!!
It's also just really fun I enjoy the two different food types as it provides a sense of strategy in which to go for, I also love the aspect of not harvesting grass for the sake of more food later down the line, it really makes you strategise for the future!!! And the den-making is a really neat way to add another mini-objective (foraging for sticks to make more), new opportunities (setting up camp near bees), and also a neat way to add in fast-travel in a way that doesn't interfere with the setting of the game!! And it costing more sticks because it requires more reinforcing the longer the tunnel is also a really neat way to explain that away!! :D
Also the art is ADORABLE I love it so much!!!!!!! I know the woofs are trying to eat me but godddddd they're so CUTE. RAAAARHHH!!! And the grass is so pretty I jsut love the kinda scribbly papery style everything's done in!!!!
And the way you incorporated the seasons is also really neat!!!!!! I love the aspect of stockpiling for the winter :D Honestly it kinda reminds me of Dont Starve, I've never played it myself but I've seen playthroughs and I love how they do the bountiful summer and spring and the grueling winter and I see a lot of that spirit in this mechanic here and I think that's freaking awesome cuz it makes it so much more fun!!!!! :DDDDD
I have no idea if you plan on expanding it or not but if you do then a longer version would be SO MUCH FUN!!!!! A full extended version would be a lot of work I imagine- but a smaller way to add more could be like different difficulties with different population goals? So like a hardmode with a way higher goal but the same core gameplay? Again no clue if you're even planning on working on it more, no worries if not I'm mostly just thinking out loud- like this game is already so amazing and I had so much fun playing it!!!!!!!! Ik I already beat it but Ima play it again >:D The map generation gives it decent replayability!! :DDD
EDIT: Also I love the sound design!! The cronch sound effect is so oddly satisfying <3 And also I love how the Rat God kinda looks like he's rapping as he's talking, dropping some sick lines of wisdom on us (and also placing the burden of our entire species on the shoulders of One(1) Rat, which is objectively hilarious)
