have you ever played mystic realm? well i have, and if you haven't then save yourself and don't, let me tell you how bad this mod really is.
first, the level design looks like its from 20 years ago and has awful texturing and some levels are just mazes.
second, the difficulty is not consistent at all, jade coast and tempest valley might be really easy but then verdant forest comes in being a very confusing maze filled with enemies, flame rift act 1 is really easy but then act 2 is a huge mine field of enemies and right after that is midnight freeze zone, which is one of the easiest zones in the game and if you know where you're going you can easily beat the entire zone in less than 2 minutes and just when you thought the later levels are gonna be easy, you get hit with sunken plant which is by far the worst and hardest zone of this entire level pack, most of the level is extremely slow and it takes place underwater with a lack of air bubbles and a ton of enemies, death pits and hazards, right after that is aerial garden which despite its difficulty its in my opinion the best stage in this pack, as the name implies you're platforming on "gardens" over a massive death pit for most of the stage which is actually executed pretty well, but what isn't executed pretty well are the enemies, the entire stage has hordes of jetty-syn's that rush towards you and can knock you off a platform or just be generally annoying and they piss me off, i am glad they got replaced with hive elemental's and bumblebore's in the vanilla 2.2 secret stage, but the actual worst part is the boss fight which is almost never in your reach and keeps flying either way too high or way too low. now we can talk about the secret stages which are unlocked when finishing aerial garden zone act 3 with all emeralds, prismatic angel is a good zone and its a fun and challenging level while the second act is really hard i still found it enjoyable, mystic realm zone on the other hand is a really hard boss fight with multiple phases and takes way too long, it gets very chaotic very fast and is not that fun, the emerald stages aren't that bad but i often found myself getting lost and taking a lot of time because of that.
third, the record attack emblems, most of them are really easy such as the time and ring emblems for the main campaign stages, the emerald stages emblems are a little harder especially the time emblems but otherwise they're decent.
fourth, having to find shrines instead of emerald tokens is an interesting idea but the locations for some of them are just terrible and some have them in plain site but require doing a bunch of steps to reach, a great example is aerial garden's an starlight temple's shrines which require searching the entire stage for multiple buttons to unlock the gate preventing you from reaching them and nowhere does it tell you about this.
fifth, the only redeeming factor about this level pack is the music, i don't have much to say about it other than its good.
overall mystic realm is an outdated level pack with many flaws and even for its time it was not that great.
