Indiana Jones and the Great Circle combat too easy? Enemies go down in three hits

I’d post this on the game’s subreddit but I can’t find one. I’m playing on hard difficulty, but enemies go down in three punches. There’s no fight, it’s really just me quickly knocking them out. It ruins the fun a little as there is no consequences for leaving stealth, it’s just an easy 1 2 pop and on to the next enemy. Do the enemies get more life/harder as the game progresses?
