Hello,
i played the game quite a lot the last weeks and going forward will give some input :)
First i want to say that you did a great job and did many things right and my criticisms are just thoughts to make a good game even better.
Some general things:
-i like the first shop special but really dislike the fact that it displaces relics, because some relics just feel good to get after first fight if you farm enough and have a bit of luck. Maybe replace some of the other card choices or even remove/upgrade/potions.
-For me many cards feel really underwhelming and there are often shops, where i don´t want to buy any card. I know that some of them have great synergy with eachother, but especially on higher ascensions you often don´t have the luxury of waiting for the right combos, because enemies like wolve eat you alive if you have dead cards (for expample energy or draw cards without the other one). I would like more solid cards that do things on their own. Maybe then you won´t even need a first shop special anymore, if these would exist, because in a way i find it sad that buying basic cards is often the strongest choice in the first shops. Also some way to improve non basic cards would be fun.
-I find myself always picking the same perks without even thinking, because after many runs i just deem them to be the strongest. Maybe you could add more flexibility like targeted upgrades or crafting a custom card.
If you want any clarifications on my points feel free to ask.
Lastly a question from my side: Can you tell, when the last three classes will drop? Even though i don´t know anything about them i am really hype to play druid. xD
