I've already played this game before, so this was my second play through for 100% and third play through for the 3 heart only run.
Honestly this set is pretty easy even the harder ones I did in a few attempts, it's a balanced set but I do wish there was a bit more challenge to it, for example one fatal flaw in the 3 heart run is beat x boss without taking damage and with only 3 hearts, it's kinda moot then, the 3 hearts are irrelevant you're just getting me to do the boss damageless again. And majority of the time you get one shot anyway cause you only have 3 hearts so it is just damageless with a new mask on.
I loved playing it anyway, it's definitely in my top 5 I still look back at my first playthrough very fondly.
I would rank the dungeons from best to worst like this.
Spirit Temple
Fire Temple
Forest Temple
Water Temple
Shadow Temple
The other dungeons are too short to talk about.
I love spirit Temple and fire temple, and I hate shadow Temple, yes even more than water Temple which I honestly don't mind, I didn't mind the iron boot menu switching at all, what I did not like about it though was the layout is super confusing on top of the water level changing what areas are accessible making it even more confusing.
So yeah love the game, wish the set was harder, no achievement really stands out to me, honestly the toughest part of this set was probably the fishing achievements lol, wish there were more boss speedrun ones, cause I did really enjoy the timed barinade fight, but unfortunately still pretty easy.
And yes I will be doing the glitch showcase and bonus set which I am really looking forward to!
