I like it! Its always amazing to see how distinct people can make their aesthetic within really tight pixel resolutions.
I hate it when people say "oh, you're making a [genre] game? You should check out ...". But it reminded me of this old game called Dinosaur Safari where you go back in time to take pictures of dinosaurs.
I like the puzzle of the frog behaviour interacting with the mechanics (digging holes or sneaking). I think there could be a lot of meaty gameplay in the space where behaviour meets mechanics, rather than jumping puzzles or avoiding danger. It reminds me of adventure games where you try and draw out an animal with bait, or block off exits so it can't escape. I think The Dig had some puzzles like that. You could add in multiple states to animals, so while it might be easy to collect data from a normal animal, one that was pregnant and hiding in a burrow/nest might be really hard to find or get at.
Biomes would be cool to see more of your art.
