It's a little too hard to tell at what point you can move up to the next size object. Perhaps placing marks on the size meter on the corner would help.
I'm not sure what the "advancement" of this game is supposed to be. It's an overused concept and you don't add anything to it. Worth noting that there are numerous spacing errors.
You really need to make it so the same condition can't stack more than once. Perhaps it should refresh at best. The second "boss" battle is basically a roulette wheel if you didn't properly assign the stats.
I've only played ~10 games and I can tell you several things need changing right off the bat. 1) too many people have the EXACT same decks. That means there are some characters that are way too good compared to others. 2) There are some card combos that are almost auto-win versus others. 3) You need more of a player base. Too many times I end up fighting the exact same people. 4) While the variety of starter cards is nice, again some are basically useless and you have no way of knowing until you get whooped.
