so to begin, you'll want to go to the options menu, as you won't be able to remap the controls midgame, this is important depending on wether you have a qwerty or azerty style keyboard, also it'll help you get a small taste of the control scheme

there's 2 very common ressources in the game, money and sand, money is aquired automatically and given at the end of each wave.

as for sand you'll have to lmanually right click on it after defeating an ennemy.

do note that in order to unlock actually useful buildings and upgrades you'll have to interact with the totem and scroll your mouse to see what you can buy, either unlocking new buildings, buying some villagers to fight alongside you or getting yourself some upgrades.

at first you'll only have acess to money and sand.

sand can be stored in stacks of 8 in specialised chests, it's best to build some early as it stacks quite quickly.

second would be power, for that build some power tower.

as stated before, this is the first time I write a guide, but I plan on writing more on it once I figured out more of the game.
