This is really fun so far! I really like the designs of the critters, they're pretty creative :D
Btw I encountered a couple of a bugs :O The path up north of banana city, going to potato town (I think?) just leads out to a big blank white space without any textures, similar to what someone else posted a pic of below.
The second was when I was in banana city, after upgrading my licence, I was able to add both the bird and fox to my party, even tho the cap was supposed to be 2. When I got back to the sanctuary I put the cat and bird on cleaning just fine, but when I tried to add either of them back to my party it said I had too many critters (even though I just had the fox lol).
Bugs aside though, I really enjoyed this, very charming atmosphere :3 (though that radio did make me very curious I must admit)
