Here is my more serious review:

For context I'm a quite good slay the spire player, the only reason I didn't grind until ascension 20 is because I got bored after a while.

🧚‍♀️What I liked about this game:
-Everything

🧚‍♀️What this game would benefit from:
-More stages and more characters, but I'm pretty sure you are already working on them
-Didn't see any fairy in the game, but I may have missed them
-The possibility to visualise which artefact/card you are offered without being forced to choose directly (like if I'm proposed the toxic egg, it would be nice to know if I have any nice skill in my card choice)
-A way to see what the upgrade of a card looks like (for example, seeing the upgrade of a card like poison arrow make it suddenly quite more interesting to pick).
-A reminder at the camp that you have a mystery essence in your deck and you may want to rest rather than upgrade.

🧚‍♀️Bugs:
-Stable orbit+ either doesn't work properly or doesn't explain well its effects, I only received radiance from it when I actually redirected an attack.

🧚‍♀️Random thought (neither positive nor negative):
-I wish you good luck to balance all of this. I got the tangle yarn on my second run, and let me tell you it is even more ridiculous than the pyramid cube of slay the spire. A lot of gems/relics scream that they want to break the game.
-The huntress' relic seems by far the best, to not say the only sensible choice. You are at the mercy of card draw in this game, even more than in slay the spire due to having 3 different colours of mana/cards. Having a good starting turn is essential. The dwarf's starting relic may be fun for a greedy run. The tactician relic is laughingly bad. No battle is ever going to last 7 turns unless it is a boss battle, and an upgrade at that point of the fight isn't going to change much. I don't know what to think of the priestess' relic, multi-enemies encounters aren't that common.
-The game is already easy for me despite having upgraded no heroes. I hope there will be enough challenge justifying those upgrades.

Hello! Welcome to Feedback Quest 7! My name's Hythrain and I'm one of the hosts and one of the streamers for this event! This feedback is being written live as I stream your game! If you're interested in seeing my live reaction, let me know and I can send you a link to the VOD once it's posted to YouTube!

So my normal approach for any game in these events is simple: I get the game, make sure it's not a virus, then play it with as little information on how to play as possible. This way, I can judge how intuitively someone can figure out the game. Only if it's obvious that I need to read more will I do so. I note this so you can get a sense where some of these feedback comes from. In addition, I want to note that feedback and rating are different; don't use this feedback to gauge what I'll rate, nor should you view my rating as entirely indicative of my feedback.

So I like me some deck building games. I'm a huge fan of Inscryption, and we've had a few deck building games come through previous Feedback Quest events. So when I started, I was excited. While I didn't quite understand what was going on in the beginning with my "learn as I go" method, it felt so impossible to reach the big boss of the first area, Titan. I only got through 4 or 5 stages before my first run ended. I expected a second run, where I now had all the knowledge I didn't have before, to see me double my progress at minimum. Instead I barely got through 7 stages. Okay... Go again! 3rd time's a charm, and I'm really getting the h- 10 stages. It wasn't until my fourth run, once I had upgraded two characters and was getting lucky enough to finish some difficult fights with one person alive, making me revive the other two, that I got to encounter the beast that was Titan.

Now I'm not sure how long the game will be; if you plan to have it you only play through 5 or 15 or 50 areas. Because of this, consider this feedback with a grain of salt... this game is way too hard as is. Enemies are incredibly strong when you're starting out. It's made so difficult to heal your characters, which can make surviving really hard. I remember getting to my first rest spot and thinking I'd be able to heal up... only for it to be 30% of the character's HP. Not only that, but you forego improving your character to try and get further in the run?! AND I couldn't use the shop?! Wha?!

My number one feedback would be to curb the difficulty early on. You're better off having a bit longer of an experience with a more gradual curve, so people have time to adjust throughout a run and not only when they've lost.

Man, I really enjoyed this one. Being a huge slay the spire fan, I immediately recognized the similarities and I really liked the twist you put into the systems. Having 3 characters with each their own energy and cards was a very nice layer of strategy as well as the jewel system, the upgrade system and the hero empowerment. Really awesome all around.

Controls wise I think it handled just like slay the spire. Cards can be played in quick succession, everything felt smooth and worked as it should.

If I had to critisize anything, it would be the  the audio and the UI. I found it a little annoying that the "hitbox" for the enemy tooltips to pop was so massive, that I felt I always had to put my cursor on top of the screen to actually look at the nice art you got going, which is bad, because my cards are at the bottom.

The one music track I got to listen to sounded very generic and the loop seemed very short, so it kinda got boring to listen to really quickly.

I think you got an amazing game in the works. Wishlisted immediately.

I gotta say your game is really polished, I find the rouge lite aspect and the game loop pretty addictive, I was able to sell it to my hubby and get him interested in trying out the demo, I hope for your success on the steam market. Best wishes. I was slightly slow on getting the fact the 3 heores in the beginning is the "team" you start with, I thought I was supposed to be pick one. lol
