Thanks for playing and giving a detailed feedback!
Yeah, I should've made it so that the Antivenom also heals HP, considering how important a single turn is.
I actually made it so the later enemies, while having the same moves, can actually use the moves more times than the earlier ones. Though I guess it doesn't really show because of the RNG, hahaha.
Having the tiles affect the story routes does sound like a cool idea! I do want to explore the possibilities with this style of gameplay in the future.
