Great to hear that the feedback helped, and you are developing this further (If you need any help for example gametesting or so i'd be in! :) )!
I think you could really go far with the things you can eat, not only things that make sense in a way, but even bigger houses, maybe vehicals (eating metal could be one of the things you need many bugs for), but its your choice how "real" you want to make the game, and if you want it to be at least slightly logical, you should prabably not read my suggestions :).
Same goes for the antagonists, i mean things like the cows obviously work well, but i thought about adding some "static enemies" like a river, with a brige where you would lose bugs (or whatever they are called :) ) falling into the river. or some really advanced enemies, like in slightly more populated areas maybe even something like a human with poison to spray. Or roads where vehicals drive on which smash you if they drive fast, but you could eat them when you have enough bugs. And to get some "speed" into the game, you could even make some kind of storm (thinking about Fortnite, where the the storm damages you and circles you and restricts the playingfield). Most of those ideas are probably completely stupid, but i was just writing down everything that came to my mind and you can see what you do with it :)
A complete other topic, i was thinking about the camera, and how i was during gameplay not sure where the map ends and where it goes further, i think the camera should zoom out when population grows, so you have a better understanding of the map as you grow.
