If you have your stats up, bats should be a breeze. If you want to forage or mine in the cave system, make a
Bat Wing and wear it when you're in there, and the bats will ignore you. (Kill a few bats, dry the wings instead of studying them.) The other advice is to be careful when mining. Slimes can now randomly spawn when mining. It shouldn't be an issue on L1, but the deeper you go, the harder and especially more numerous.
Overall, sounds like you're doing pretty good.
Metal is that turning point to make hunting and food better. In the mean time, you can get some domestic animals to get milk for cheese and a few other foods, maybe breed for meat and materials. (Keep your herds culled, though. They can get out of hand fast.)
