Thank you very much for your comprehensive feedback @sergi-montaner!
To adress your points: +Are you sure, that you couldn't summon a creature? You should start in the spawn phase, where you can summon something or skip that phase, next somes the main phase where you can cast spells and attack with your monsters. Something like hearthstone might work yeah, but also like hearthstone some option to skip/end turn is neccesary, because you can cast as many spells as you want and the gae cant find out, if you are done, or you aren't.
+This behaviour is intended (so it is not that big of an advancement, if you draw more monsters than your enemy at start) and I thought it was clear by writing "spawn A monster" in the log, I will change it to "spawn one monster" so this gets clearer.
+I will definitly make the life more prominent in the next iteration, since this was critiziced by quite some people already. I'll also try to switch the players position with the battle logs and look what I like better.
+Good point, I should definitly change the colour, just like you did!
+This was included in the design because I intended to make animations for drawing and discarding, but I didn't made the jam version. Hopefully will be part of a later version, otherwise they will probably be cut.
+I'll put a different background on my graphics TODO list :)
+and lastly feedbackwise, just like the draw/discard animations this is pretty much the next thing on my TODO list and I am currently working on it.
Thanks again for the great feedback, I definitely plan on keep working on this, so every feedback is well appreciated!
