DISCLAIMER:
This review is entirely for my own sake. You are welcome to read it but it may or may not contain spoilers for the whole game.

NOTE: This review was written moths after I finished playing because I had forgotten to write it beforehand, so some details might be wrong but my general opinion of the game stayed the same throughout the experience.

I went in expecting a roguelite game with cool meta progression that would allow you to get further into each run and let you find more and more secrets. I found a mediocre roguelike with a couple of simple "secrets."

There are many spells, which would be a good thing if it weren't for the fact that changing between them is a real hassle, so you will probably end up using just a couple of favorites and whichever ones are required for the titular secrets.

These secrets take the form of mini puzzles that are guaranteed to appear in their respective rooms. These vary in difficulty and complexity, but they ended up feeling quite disappointing. See this chest behind a glass door? Throw something and break it. See this chest through a window? Fly in throught he window. See these colored plants? plant them in the same colored pots. All quite easy to find as soon as the map tells you there's a secret in the room. And then some other room hits you with having to turn, with no indication, one specific wall decoration that looks the same as the ones on every other hallway. Why? They are also not helped by the repetition. All of the puzzles stay the same, in the same rooms with the same solutions every run, and if you want to play optimally getting all available resources you will have to input the solution you already learned over and over again.

This repetition alsodamages the feel of the combat. Each enemy is well designed by themselves, and it's interesting when many of them attack you at the same time; but you can generally pick enemies off one by one, and I can only fight the same 7 enemies so much before I get bored of the same patterns. More variety would have been nice.

I didn't get to have that same repetitive experience with the bosses, but it might be because I didn't do enough runs. You only get to do a couple of boss fights per run, after all, while you fight basic enemies by the hundreds. The final bossfight I beat twice: Once I was so overpowered I just stunlocked him without even having to learn his patterns, and another in which I had a good run and I managed to pull it off by the skin of my teeth. All other 5 runs where I reached it with decent or mediocre set-ups, he demolished me without even giving me a chance.

And there's the thing, you can't control how good your run will be because of the random upgrades to your spells. The game tries to always give you upgrades to a couple of spells at the time in order to encourage creating synergies, but if you happen to get slight upgrades to your utility spells and none for your damage spells you WILL be in trouble. It sometimes felt like the more spells I unlocked, the less likely I was to get the upgrades I wanted/needed to succeed.

Which brings me to the meta-progression. Currency is scarce, and there are many places to invest it. You might choose to upgrade your base stats, upgrade the shop, buy new spells or slightly upgrade one that you already have. To learn new spells you must rescue teachers during runs and it gives you access to clubs which seemed neat, so that's what I chose to do, but they just allow you to start the run with one upgrade and one potion of your choice. You can also rescue classmates during runs and talking to them in the hub gives you... just some basic tips or flavor text.

The characters themselves had no personality, which is what happens when there's so many of them and they only have a couple of lines each. And the story seemed non-sensical, although it is given through a couple of lines at the end of each run, so I might have not seen enough of it to get it.

Every time you beat a run, everything gets a tiny bit harder and combined with worse upgrades because of too many spells made me not want to play more to get to the 10 runs I was asked to beat for what I assume is the end of the story.

Overall, too much spell variety makes it too RNG dependant and too little enemy and room variety made runs long, boring and tedious. Would not recommend unless extremely desperate for a magic themed roguelike.
