It does sounds like you might have a hard time finishing the game, but the thing about this game is to build the muscle memory required to deal with the enemies. Dodging should be instinctively, because the next level and final boss is literally chaotic, or rather bullet-hellish.

I'd say this game is much fairer than any other roguelike, which rng can be quite brutally unfair. It take me a bit longer than 30 runs to finally beat the game once, then the subsequent time is easier.
