In general I really like card games (and especially slay the spire) and I think there are several characteristics of the cards in your game that make it interesting
Some good points:
- The illustrations
- Interface design
- Although the tutorial is a bit long, everything is very clear
- Character interaction in battle
- Balanced card effects
Some points that I did not like:
- I think it would be better not to apply a punishment when using a first aid kit (you are already punishing when removing a first aid kit) and it does not encourage you to use them
- Having to wait for animations to be able to use the next card
- Limit to only 3 cards per turn and not have an "energy" mechanism that needs to be managed
- You could have more decision options before a battle
