I'm stuck and don't know how to move on.

[Rossy]

Every path is blocked and after some time I've got really tired of playing this game and I'm about to quit. So I decided to ask for a hint because I like this game and I don't want to quit it. Here is a screen of my map. Do I have to buy something to jump higher or dush or something? Also I have City Crest in my inventory. Do I have to locate that to move on?

Okay so, you need to beat The False Knight, which it appears as if you have already done.
Thereafter you need to talk and agree with the Shaman, it'll give you a Soul Spell, which makes you able to shoot attack, by the cost of your Soul.
When you're done with his "Chamber", then continue over to the left side of the map.
On the vertical room, next to the Grubs.
There you'll find a room on the left with one of the bugs from the Shaman "chamber".
Just attack him with your spells, and there. You can progress into your next area.

How did I miss it. Thank you guys. Now I feel even dumber.

I started playing it recently too, but I think I can give you a tip for when you'll feel lost. As soon as you complete an area/get new powers and you don't know where to go next, talk to Elderbug in Dirtmouth: he'll give you hints on where to go next.

The tip with Elderbug helped me too, it's a nice advice. Sometimes it's hard to decipher what he means, but you can always google it. If he keeps repeating the same clue, then it means you missed a key game ability in that area.
