this is really unique. im usually not a fan of these type of rougelikes but for some reason i like the combat. a few rapid fire ideas i have are as follow
1. make it to where not all cards have to be dragged to be used
2. because all you do is move forwards backwards and left click stuff i would embrace it and instead of using W and S keys i would remap it to the scroll wheel and make the end turn button be the right click.
3. my computer is not the best and the game was a little choppy in its frame rate and for some weird reason it added to the atmosphere on the game.
