Okay, I just lost a match against a Level 5 and I have no idea why. Granted, I had 20 HP left, but here's the story. 20 HP left, 5 Cards left (NOT in hand, in the DECK. Had about 4 more cards in hand)...finished my turn, pressed Space, then suddenly I lost. It makes no sense because even if the enemy's attack was enough to kill me, it should have at least showed the damages being made. There's no way that the enemy's first attack killed me because that would only happen if they had a monster over the dmg of 20... it didn't. Besides, it didn't even SHOW anything about the opponent's turn. I just pressed space bar and I was immediately dead. I'm 100% sure that I did not lose because of lack of cards. I JUST looked right before pressing space and I had 5 cards for sure. I'm... really puzzled.
Putting that aside, it occurred to me while staring puzzled at my "You Lost" screen that there's really no need to have a whole new You lost screen, is there? Could there just be a little pop up message (like the one that comes up when you're using spells with targets) that says "You Lost" and a button for the menu? This way the player could actually look at what the hell killed them... Idk, just a suggestion because I DO see a lot of posts like this where people say, "what the heck killed me??"
