Finally got around to playing this. The game starts off fine, but...never really goes anywhere. The new spells you get are passably interesting in that they offer something for both combat and exploration, but nothing that your standard knife and magic bullets couldn't handle for fighting monsters, and they're strictly only used for gate-keeping in terms of exploration. There's no real puzzles in the game apart from finding matching colored crystals, or finding a key to open a locked door (save for a single instance in the game where you cut a rope to drop a hanging block to reach a platform). There's a maze-like section where a grid of platforms is sectioned off by colored blocks, but it's more tedious than fun, in my opinion. All in all, a huge portion of the game is just traversing space with a lot of filler mobs. Character progression quickly becomes locked behind skill books, which I couldn't be bothered to hunt down, so I just sat on my pile of 20,000 mana at the end. The stage designs are really uninspired, too.
The game is an improvement over Ernesta, and there's nothing egregiously broken about it (there are some bugs, such as walls which aren't solid which can lead to you getting softlocked by becoming trapped inside of the terrain), but it's hard to say that's it has much to it that is fresh or exciting. I feel like the choices for bosses and their loss scenes were pretty boring overall, and the normal enemies quickly wear out their welcome with how often most of them are used - and one of them is a palette swap at that. Game is much slower and bigger than it needed to be, for how much content there is in it. I didn't hate it, but it did become a bit tiresome to play through past a certain point (about halfway through the forest stage, really).
