It would be great to have to survive against :

ticks, centipedes, praying mantis,earth worms, squirrels

for building maybe add some stone structures and balconies maybe some rope ladders to get in-between floors of bases 

A blueprint for a raft would be great 

and maybe a Sword of some type made from centipede parts like legs and she'll for armor like the lady bug set but tougher and stronger

possible saddles to mount insects if possible to take in future to use for travel 

I like these! especially the building ideas, maybe add some single wide stairs and a roof peak too for those random builds that end up three wide.
