how does one get better at roguelike games ?
so i'm not really new to the genre. i played some games with my partner and somehow i sucked in all of them. he was really good tho, alone he could finish in a couple of runs. he made good choices when it came to upgrades and then there's me, i feel stupid every time i have to make a choice. like whenever i ask myself what build am i going for ? or which upgrade would be best, i end up making bad choices so i pull my partner down with me and we end up losing. he used to enjoy gaming with me but now he just can't because he thinks that i don't understand roguelike games and i think he's right but i really want to improve ? like how does one learn to make good choices or better how does one figure out the "best build" for its character ? i'm open to all suggestions
games like : hades, roboquest, don't starve together, teenage mutant ninja turtles.
