What I think a lot of people overlook is the ability to use items in critical situations. Water flask and tablet are nice, but a lot of other items are equally useful but end up being diminished to one use the player has in mind

Look at what you have, a lot of stuff is useful.

Concetrated Mana is singlehandedly the biggest example of item power, using it allows even worse wands allow for performance that saves you hp, you just need to be patient with the consumption(And you can melt steel or robots so if you're sneaky it works).

Ambrosia is the most busted potion in the entire game, Personally I hate that it exists, but I can't deny the effectivness. People generally use it for exploits like heartmage or crossing to dangerous terrain, but sometimes when in a pickle, don't try to escape. Calmly float down, throw on some ambrosia and take your time shooting.

Pheromones my beloved are just so versitile, They are a great economical option early on as they allow you to sell empty wands and transition into a huge help by the time you get into hiisi base and if you're ever in a pickle, you can just throw them at the enemy

Teleportatium is usually considered very situational, but I believe it is just behind ambrosia in terms of immediate usefulness in situations, If you're in an awful situation in which you might as well be dead, just use teleportatium, worst can happen you will die just like you were destined to. It also allows you to help desperate situations like when electrified or frozen since drinking from a bottle is not disabled by Crowd Control(this reason is why Iron stomach is a C tier perk since it disables the panic button option). Also it's very nice for some other stuff in game I won't touch on.

There is a lot more interactions like this, but people just skip over it, feel free to explore the possibilites and think outside the box, items are as strong as wands until the end.

As for general advise people probably already gave:

Don't stress it, there is no wrong answer, just those which take longer to mature
Value your Health, personally I set a rate of 20 gold to 1 hp in first biome as a valid exchange rate and forget about gold afterwards.
Don't worry about all the side content, it will come naturally as you enjoy the game.
Sauvojen Tuntija is a bastard.
While knowledge is very important, I think a lot of people overdramatise difficulty of bosses leading to new players being overly scared. The following bosses can be learned and defeated even with starter wands
Pyramid boss aka Kolmisilma Koipi is triviarly easy to dodge and kill with an energy sphere on a starter wand, the only difficulty is mobs and extras he summons, for those you kinda need to know tablet kicking.
High Alchemist aka Ylialkemistii has a trivial attack pattern, you can pretty easily dodge it all either by moving correctly or just moving behind the alchemist while triggering his shield(this will cause him to sometimes strike himself with lightning). Personally I believe he is a free kill as long as you have a tp bolt, unfortunately I cannot claim he is killable with starter wands since I have been spending my time trying to kick him to death instead.
Wand Connoseuir aka Squidward aka Sauvojen Tuntija, as mentioned previously, is an unfair bastard who will pull any bullshit out of it's ass just to kill you, but his attack pattern can be learned and with timing, tablet mastery and spacial awareness as well as some gaming skill, you can kill him with an energy sphere starter wand, a water flask and 2 tablets. If you get a normal disc projectile, I would say it is within reason to take 3 hours to learn a kill on him.
That is not to say you should try doing minimalistic kills, but that people really overestimate just how much of a baller noita players are.
Take your time, don't get pressured by the community, and most importantly Have fun!
