Hey I played your game and is working well. Here's my feedback...
- nice start menu, good easy to understand layout
- sound effects a bit jarring
- music doesnt quite feel like it fits
- a quick start option would be helpful
- maybe player should have a starter deck
- the cut to pack feature was cool but got annoying, maybe it could be more forgiving
- great card art and really cool to see that some was even animated and have special sounds
- music slider doesnt work right, i cant click and drag
- once i got my cards and deck in the game, the screen doesnt fit on my monitor, I have to zoom out.
- am somewhat a fan of card games, i play mtg on occasion but i did not fully understand how to play, a tutorial would help
- i am playing on easy and just click a card and click attack and i seem to be winning but not sure why
It is really cool to see all the work and detail you put into this game. Just needs iteration and refinement but this is a great start!
