Yeah this one is hard. H-mechanic is mash attack button (x) to escape, but it drains your health while grappled so you only really get one go.
The first boss needs you to get the thorn whip. You needed to go down and to the left in the cave instead of rushing the boss. The whip takes her down in 4-6 hits.
(a sense for locating secrets and hidden things that i developed playing LOZ when i was a kid gained me the whip and several hidden bonus orbs already, did you find the one at the bottom of the pit that you have to crawl into a hidden tunnel on the left of the pit to get?) edit: look for a spot in the thorn cave where the water splits on a pillar and the right pit has an enemy being pounded...the other side is the pit with the orb.
that would be handy if i could get near her, but the dumb rock drop attack, vine and then while im recovering from that, the leaf attack generally keep me at the back of the arena until i get grabbed and die...i grew up on side-scrolling platformers, and there are too many times where i have to take a breath and accept that the game was designed to punish you...its not difficulty to get hit by an enemy you can not see, or could not avoid...its bad game design to put the enemy there in the first place, and that compounded with controls that fight me every step of the way...i just dont know that the game is worth playing...at this point its a boxing match with me VS disinterest.
Edit#2: nope, even knowing that the whip kills her in a few shots, i was killed via stunlock several times before being able to get more than 3 hits in and i just find this game to be unacceptibly frustrating...i love the visuals, but wont be playing this game legitimately, instead im just going to open up cheat engine and find the health values...also the sex mechanic only works like 1/2 the time, and when it does work, it just sits on repeat until you try to fight it and die for me, i dont know that this is the intent, but i have been doing a virgin run because i cannot survive the convoluted H-system the author used...i really wanted to like this game.
i love the idea of playing as a cute witch, i love the setting, the combat mechanics, and if they were executed in a way that i can describe as "not like being fisted by the hulk" then id continue...but now im going to cheat, just to see the content beyond this headache of a boss...il edit this if it improves, if not, i dropped the game.
