general tips - 1. at the start, put all points on constitution. 2. don't worry about money, as it becomes obsolete very very soon. 3. 'claim money' button stacks with each cycle, overall, you might need a total of 300k$ throughout the entire game. 4. 'cleave' is by far the best magic. at higher levels it will one-shot anything, even the king in level 50 of tournament.
I consider myself an idle game lover. and this game - it's pretty lame. less lag at higher levels would get more appreciation from me, and other things to do with the shop, maybe more side quest tabs or something, learn from other idle games, graphics is good, not great. not even animated. UI looks great. smaller improvements you could do - 1. using a slider to choose floor, instead of L/R buttons. 2. countdown to magic refresh. 3. numeral HP above you and opponent. "buy all" button in shop. with a bit more work this could be the same genre as 'sonny'. tl;dr
I'm at phoenix 34. i'll call it a win. to the developer. my two cents -- graphics is cute and compelling. 'quit' button is terrible, should be changed to 'back'.
game itself it just an 'idle mine' replica, which is boring. all you idle programmers out there should really learn from 'cookie clicker', which, to me, is one of the best idle games. and the endless (i presume) phoenix battle is quite annoying, let me win in peace and not feel like i ran into an infinite loop software glitch. one other thing, top monsters should give more crystal. all monsters give 1 crystal regardless of their level, removes the incentive to tackle the big monsters. so it's stupid, you could win by one shoting the first monster in the game. and it would take you EXACTLY the same amount, if not less, Time to finish the game.
i would raise the price of the higher upgrades, and let each island add a +1 crystal bonus. and as i said, the graphics were great, the mechanics were boring and unimaginative.
played till i could one shot the last planet... enjoyed the game. could use better interface. but still great. people like me will play all idle games, but this one is not that interesting. check out cookie clicker for a reference in the future :) my2cents
