I think you should add a lawn, a basement, a lake and a cave to make the game more interesting. For insects, add spiders, earthworms, mantises, crickets, caterpillars, butterflies, dragonflies, frogs, snakes, beetles, ladybugs, tapeworms, moles, voles. I thought about this all night and hope it will help you in the next update. I hope the new update has a lot of good things and please give me your f95 link.
The author has said many times that there will be no spiders because many people do not like them. There is a chance that there will be something similar to them, but there will be no spiders themselves. Read this and other sections. There is a lot of information about what will happen and what exactly is not. Otherwise, the ideas are interesting
