oh you are 100% right. The enemies are not at all balanced. I think I can post a table with the effects of the animals, but I remember doing that very last minute.
You see, I made this as my first roguelike, for the 2020 7DRL, in 7 days, and I tried my best to cram as many features as I could in a week.
Like you, I really love the concept and I will absolutely revisit it for next year's 7DRL. Given that there is at least 1 person interested, I can try making small updates here and there, but I'm busy trying to make a different game right now.
Thanks for your feedback. And for playing :D
