Evolution points are to much of a problem. to fix... A) this is my favorite, Remove it entirely and just go on levels and a clean, well fed monster will get more EXP than a neglected one(25 for flofox instead of 15) B) 12 hours instead of 24 C)evolution stones cost much less. D) some combination.
a number of bugs make the daily challenge virtually impossible. 1.)If you have a battle all visible monsters disappear. 2.)The arrows still point to the nonexistent monsters. 3.)It doesn't show what you have beaten and not. 4.) the timer doesn't stop when you have defeated all monsters (not sure about this see 3).
better animations, "wobble wobble bonk (puff of flame only vaguely near opponent) wobble wobble" Just doesn't cut it, maybe moving legs/wings would help and the other Terra Monster reacting to attacks at all will be a start.
