Oh, I think I understand now.
It was indeed my intention to leave the players to experience the game and gather informations on their own, so they can slowly start to understand the game as they learn more. I, personally, kind of like that way of learning, but of course it's not ideal for everyone.
I'll try to balance it a bit thanks to your feedback by adding some guidance at the beginning, when the game is played for the first time. I think the message will tell the player to wisely choose enemies they want to battle, to learn about new tools and utilize them and to gather enough strength to progress through the portal (you would find it if you follow the path). It should be enough both to give the player at least some directions and not ruin the way I'd like them to experience the game.
Story wise, as I mentioned earlier, I think that infos from the intro cutscene I'll add in the future will suffice, but for now I have to leave it as it is.
That said, this game is quite complex, which definitely sets a kind of barrier for a new player. Only by learning and memorizing new mechanics and content we can make a meaningful progress. It can cause a confusion and frustration, but I am careful not to make it a "tutorial festival" too.
I will try to make it more player friendly eventually, for example by using special animations in tutorial and by using popup windows when some of mechanics are encountered for the first time. I predict this game to be in development for about a year or more, so it will change a lot for sure.
Thanks for providing more details, it's the first time someone brought that issue to my attention, so it definitely helped :).
