Thanks for trying it out! I will fix the input detection for attacks (I only found this out recently because I always used a gamepad for testing). Obviously you're not supposed to be able to charge two weapons at once, I will fix that.
But I won't change the dash. Unless I'm misunderstanding your statements, the timings are as I intended. The player should only commit to making an attack when they think it is the right moment, because there is either a long buildup at the start or long follow-through at the end, or a bit of both, so they can get punished if they misjudge their distance to the enemy or the timing of when to press the attack button.
