Yes, I agree. Many of those things just scream out to you to either annoy you or to realize, that whatever you were trying to do, actually was a hard way and there's an easier solution. And yes, invisible blocks happen. Like that one in stage 5 for example. I know it is there but I nonetheless get caught by it so often and just plain die.

I'm happy to hear my guide was of some help then~
Also, that's interesting about phase 2 of that boss. I think I never tried to take on this one clever way, and was jumping randomly trying to avoid all of the spikeballs. I'll have to look into this one. Thanks for heads up.

I have seen this boss being done by jumping around a lot and avoiding everything but I doubt that safespot was accidental. This game has so many things that might feel accidental or mistakenly placed but a lot objects and places makes sense once you figure them out. I have seen some YouTube videos of Eryi's Action where players completely miss invisible block first but find it after several deaths and blame it for appearing without no reason and out of nowhere. "That didn't happen last time!" describes those moments quite well.

Anyway, I totally would have missed that safespot without achievement guide.. Actually I missed it based on only reading the guide but noticed my mistake when I took a close look on this screenshot. And talking about safespots, the one I'm using during 2nd phase of this boss is completely on the right side (it isn't only safespot during 2nd phase but easiest to remember), this way I can jump only during bottom spikeballs just like in 3rd phase of the boss.

Yup, that's pretty much it, I thought it feels like cheating as well. I wonder if that safespot was intended or accidental of the game creators.

That made it so easy it almost felt like cheating. It was almost as easy as staying on right side behind boss... Hardest thing was to not jump too high. Very helpful screenshot indeed.

Ta gra ma też podobny poziom trudności jak gry z pegazusa.
A ćwok z prawej też tak się zachowuje jak go opisałeś. Nikt go nie kocha.

wygląda jak gra na pegazusa.
ps. ten boss wygląda jak poronione szczenie godzilli z uchyłkiem na umyśle
