The developer of one of my favorite roguelikes says that visual issues were left in the game because the hardware they used to make it was literally too rubbish to let them see the mistakes they'd made.
Casey Yano is co-founder of Mega Crit, the studio that made the acclaimed roguelike deckbuilder Slay the Spire. The game's art style is pretty simplistic, to say the least, but the design excellence behind its internal card game systems more than makes up for that - in fact, much of the community has fallen in love with the style, and some even opt to include the game's work-in-progress card art in place of the real thing.
