La Mulanai got tired of making no progress and took a quick trip to the wiki to answer at least some of those question,turns out one of the chest i couldn't open needed to be open by interacting with an invisible dais,what the fuck game?

the game kinda tells you the location of it but how was i supposed to know that the thing i was looking for was a dais and not just a place to hit with my weapons?
then i used the wiki to find the third boss and this too made me angry because
spoiler (click to show/hide)
i tought weyjat would be some statue but it actualy turned out to be that stupid eye-trap thing i ignored because i tought there was no way to interact with it since there was one of those stupid seal in the room!
then i found the helmet (turns out i actualy passed in front of the shop that sells it but didn't notice because i tought the shop was an actual element of the background) and somehow cleared the whole aqueduct area without any help from the wiki and got the first seal key
then i used the seal key thing on the third area and it gave me an hint of how to find the third boss after i had to use the wiki to find it which annoyed me even more
then i found the 6th area and the thing is shrouded in darkness and the only way to traverse it is to fire a sub-weapon whose ammo cost a lot of money oh and the whole thing loops in itself because fuck it! it still wasn't confusing and stupid enough
i swear this game was made to give the player an aunerysm... having found 4 boss so far i must admit that this game catches the 90' konami visual so well it might as well be published by konami itself
