as someone who spent time as a kid playing the YuGiOh Duelist game on the GBA emulator i had no problem figuring out the game controls, rules etc.
i think your game stands out in terms of polish and fun -- it's fun (at first at least, i'll explain later) to see the stats you chose for philosophers and have the fighting be a debate. Quite polished considering the given amount of time - -from assets to mechanics, there's a lot of things all working as expected (except maybe the deck building which had some menu items that do not work)
My complaints will be mainly in that the theme is a bit tangential, and i know the gameplay is probably unfinished but it might've been better to split the efforts differently. maybe save the deck building for later? -- just so that the core gameplay will be fun for more than a single run. i got bored on the second game already since the mechanics are simplistic but most importantly -- slow paced. so basically making the gameplay a bit more fast paced is weird and tricky thing to achieve in a card game but it really bothered me that i didn't want to play another game but wanted to read more dialogue or know more about the characters themselves. so it kind of felt incomplete in that sense. if i had to point to something technical i'd say something about the benching is really slow paced given they had a single purpose as far as i could tell. this of course can be compensated by say an effect system (like trap cards in yugioh games) but again all i'm saying is that it might be better not to introduce either benching or deck building in this very initial stages of the game.
But yeah that's not to say that the entry isn't good; i think this is a good entry that evidently one put a lot of effort into.
