Terracore Impressions

So first terracore autobattler for me so not a lot to compare with.
Regarding graphics, a little too low, if you're not in full screen it's too difficult to read.
I had trouble to start the game. Minted one pass but couldn't select it. Minted a second one and then I could start the game.
For the UI, I still need to manage / understand when I can upgrade the potions / characters.
I also had difficulties to understand that I had to re mint characters if they die on the battlefield.
I don't know if it's a good thing to display the rank of the potential opponents in "battle", it allows you yo choose a less well ranked opponent (maybe the rewards are less important if win against an inferior ennemy).
Regarding the gameplay, it would be cool if my team and the opponent's one would be in different colors, even if the characters number is displayed and we see it decrease, a visual of the troops could be cool.
