would be nice to include something like "only pick up crafting items you need at your current crafting lvl(or for the particular branch of clothing you need)"
in theory, you should be able to get 600 in survival by taking ice and divine trees by freezing everything (not neccesarily killing) and ereasing enemy bullets, but it would just be too boring without the destruction from fire!XD
Loved the game. My only complaints are the amount of wins you have to grind simply to play other races (it'd be a lot more satisfactory if you had the races earlier on and unlocked more cards gradually) and the speed the game runs. It would be great if you included options to skip battle scenes or simplify the battle etc. 16 fps is just way too slow (with a decent computer). Keep up the good work!
