We’re not quite yet in the territory of long boss fights with no way to recharge.
There’s not a lot you can do to the Chykka Larva, what with how quickly it’s invincible again. All you really can do is just shoot it normally and hope it goes down eventually. The plants it’s riling up are thankfully so weak that I can just totally ignore them until they’re blocking my shots. I’ve definitely grabbed more than enough energy tanks for this difficulty mode and point in the game. The only things that I’m worried about this point are the last three bosses; I don’t recall anything else giving me a hard time.
This boss was a bit of a puzzle boss, but I can’t call it “the” puzzle boss because that’s exactly how the final boss of the third area plays. Rather, I would call this the Boss of Obscure Weak Points. To obtain the first one, you have to scan it, but you rarely can hit it anyway. And then for the Adult phase, the scan doesn’t give you enough information to find out that its weak points are on the back of its wings. That would have been nice to know! I definitely don’t like looking up a guide in the middle of a boss fight! I normally wait until the thing has killed me at least once, but it’s not like it was doing enough damage to achieve that. Sorry for clipping things from this fight, but I only removed parts where nothing happened except growing frustration.
