This was so much fun! It reminded me of Duck Life.
I think it would've been nice to see how many days were left in a bunny's current life cycle / how long they were going to take to hatch. Losing a race because I thought a bunny was going to be seasoned for one more day was not a great feeling. Alternatively, it could've been nice to have a small (2-3 day) window where you could choose when a bunny retired.
It also would've been nice to hatch eggs / feed on the morning of mandatory races. Sometimes I would have eggs ready to hatch, but since I wasn't on the screen where I could hatch them prior to the race, I would auto-lose the race or be stuck with some chump of a bunny. I suppose that's intentional with egg management, but personally I would've preferred to be able to use eggs I had ready to go day-of.
I'm not sure what the exact balancing numbers on this were, but stamina/chutzpah felt useless compared to speed. Dashing was a lot of fun, but I never felt like it would make a good difference in my chances of success compared to just upgrading my speed. Stamina would have felt more important if it gradually decreased over the race, even if you weren't dashing.
I would've liked it if food stayed selected after feeding it to a bunny rather than needing to reselect an option for each bunny. I know you're not always going to feed every bunny the same thing, but it would've saved some redundancy.
Overall, it was a really fun game, and I'm super glad to have found it! The bunny names were great, and the assets were put together in a really smooth way. I think I played it four times in a row, and I can definitely see myself coming back to play it more!
