Okay, here's a tutorial on how I survived the first steps, 1 equip the rags from your inventory for extra defense, now, farm 1500 coins and when the merchant comes out buy the club, although here there is a digression, if you get it before getting those coins buy the cans of food since the main mechanic of not dying in this game is to conserve energy (the summoning is a trap at the beginning of the game, it kills energy quickly which leads you to rest and waste food) if you run out of food bar you lose the game, which brings me to the next thing, every time your energy bar goes down you have to rest, but don't do it if your food bar is very low or you will die, in that case first eat and then rest.
Once you understand that, always buy bread, cans of food and healing from the merchant when he comes out, at least two of bread and cans since his appearance is random.
Once you've mastered this, you have to go to the lower forest where you find the doctor, the cabin in that same forest where you find the goblin builders, to the lower desert city, talk to the bald merchant, then go to the plateau in the desert and save his daughter, return to him and unlock a cure for the pink screen, since as far as I go I found three, in that desert city, in the cave in the forest almost reaching the snowy area and in the castle.
Knowing that, it's already a matter of any RPG to grind coins to rebuild the buildings and hire goblins.
PS, if the game warns of a powerful enemy guarding a place, they'll surely kick your ass at the beginning, so better not even enter.
That's all, if there are errors, English is not my mother tongue and I used google translator for this guide.
Question for the creator, will the new map with the elves ever come for free? Since I just started, I like the style you gave it with the energy and food bar, since it leaves health as the last thing to worry about XD
