I can accept the choice of not being able to remove skill cards... though there is a lot of reading and evaluating to do before you even know the game to get anywhere near a chance of completing the quests while still having a reasonable deck and not having to depend on pure chance however somethings that need work and are clear design mistakes (from my perspective of installing this from the itch app and launching it on my own machine):
- the Life / Food / Gems bar is very small on the default sized window that comes up when you run the game and still small on such a large screen - so many times I've made a mistake because I misread the text.
- I didn't realise until far too late that the three by three layout is necessary to understand the "adjacent" cards because the window opened with the cards in a single line but then often didn't affect adjacent cards1!?!
- the term "in game" being used (grammatically incorrectly and) to refer to just the cards infront of you completely threw me as I would have expected it to have the same or a more encompassing meaning than "deck" but no... I would suggest switching the term "in game" with "in this hand" or "dealt" or "on the table" or "this deal" or, at the very least, "in this game". I would not be so harsh if the word "game" was not so obviously a very broad term in English.
I understand this was one of your first, if not your first, game but that doesn't give you an excuse not to upgrade or fix it; and the reason for the less than stellar comment is because you are succeeding despite yourself - you are creating good games which have small problems that you are not fixing which stops them from being great games; the graphics, UI, audio, concepts, everything are great but it is let down by small problems that then go unfixed despite being reported (and, yes, I am having to comment on other games here because I don't know how to comment across the board on all the games of yours I have tried because this is definitely a recurring theme... they are like AAA games that the dev didn't bother to fix!
Your long term reputation will suffer even with your successes and so if you ever have more middling games you will suffer all the more for it. It's a shame, you could be so good...
