I played the tutorial and a couple of stages with the warrior. There are some interesting mechanics with the cards. Reminded me of Slay the Spire.
Im not a big fan of a lot of reading in the tutorial in most games. I like it when you can just play the game with very simple enemies and learn the mechanics step by step by introducing simple cards and enemies like you did, but with less text. Also, there is way too much and unnecessary information when you hover over a card. I am pretty sure you do not need to explain what HP is. Then some QOL, like when you hover on a card or item and you want to hover on the one next to it, but you can't because the information window is in the way.
