A "Classic" Game as it is kind of Old so some amount of jank with less handholding should be expected.
What should be understood first is what is the Goal of the Game as a Game.
Since it's an "Auto-Battler" Combat with a Raising Sim Management aspect and no direct control outside of some behaviour scripting.
That should give you an idea that it is about making Builds and Strategies and Testing them.
Now you can still do some amount of micromanagement, especially in the early stages and it might help you figure out how the behaviour works. You can put it on Slow and try to analyze your Character's actions and the opponents actions and see what would be a good strategy to counter that. If you die it means you have a problem with that encounter so you need to figure out how to handle it better. Once all encounters are handled well with a build that works for most that's when you can set things to Fast and press Ctrl and watch as Towers are Conquered easily.
For the whole multiple playthroughs thing, that might lead to another misunderstanding so it's a good idea to know what to expect from a First From Scratch Playthrough.
You might have noticed that initially you do not have much Mana for spells so for the first playthrough you need a Weapon.
They all have their advantages and disadvantages and some may be better than others.
There might be some obvious traps like if they have too little uses with low damage and no AoE so don't expect to clear towers with them, but they can be great for Duels in the Tournament.
The Tournament also has enemies that can give you an idea and what kind of builds are good and their weapon advantage that you can try.
For my First Playthrough I have gone with a Hammer Build and I had no problems with clearing towers and it also has some good High Damage Skill and even better AoE later in the skill tree at the cost of some mana, although kinda slow and not as nice for Duels.
Although you won't be winning the Final Tournament in the First Playthrough since Viola is Hard to Defeat, you should not have a problem with the rest.
Once you can reliably farm the Queensbell Tournament you will be racking in the cash and stats. It's also necessary for unlocking Elle and the Adept Mode with better inheritance so that is a good Goal for the first playthrough.
Some extra tips:
Take all the level 1 passives you can, some give you 5 stats at level 1 of the skill like Defense.
Set most of you Skills to Off and experiment with the Distance Range as most weapons work better at some, only enable what you need for that build and strategy and maybe set abilities that use mana to Secret.
Bosses in Towers are a Stat Check, either you kill them fast or they do, so do more grinding for health, defense and attack.
For later Towers, you pretty much need a certain magical skill to sustain you.
If your build is screwed in this run which is possible depending on the skills you invested, you can try again in the next playthrough with at least 30% bonus and respec. A Respec is a good way to think about it.
