it's hardest until you get fire and then ice storm, and then have spells like fools gold, ice/fire storm, eternal rage, and maybe healing fire and lets say life leech (as fillers). After that it's all about clearing field from certain type of gems, receiving mana and doing damage + gathering heal bonuses from 4,5 straights. Later change healing fire and life leech with poison and energy storms. Also, aim for that 15 rage / 40 damage weapon and armor with regeneration stat (so every time enemy attacks you heal half of it or so ..), higher rage weapon - less time/turns goes for attacking/rage dumping. Anyway, managed last 5 levels pretty much with maximum of 100 life lost (of 499 currently :P)
it's all about resource denial. My deck has not so many damagedealers (some costly ones and ambushes only) but a lot of +recruit/mage/builder, schools and from other side resource denial for enemy = lot of sacrifice 1 for enemys 2, curses and thieves. And to finish it some pixies and big castlebuilding.. Try to learn how hard mode computer plays , it's frustrating, right .. so learn from it :)
you, arenlor, have some strange laptop, mine definitely doesn't have this behaviour .. maybe update drivers , search google for some information about the strange behaviour ?
last levels : whole tank was 2 leech and 1 machinegun, no other parts , no bubbles, only 3 yellow guns. Killing some bigger tanks was like stand in one place and keep shooting, while watching some tv show .. like , where's the challenge ?
upgraded king hp to 1000 or so, then damage to max, then armor, spells are unneeded,
every game using archer as main damagedealer - rate of fire upgrade owns . in 2 last levels also some lancers as best meatshields and healer+spirit aura mage ... walk in the park ... so, serious balance issues, but game itself is nice and balance should be easy to fix
then again, considering that this mortar type cannon can bring down +100$ balloons, thats probably a way to make more money without even watching the screen ...
well here i am, in game level 7, no more children appearing, yet the counter in left upper corner showing 16 :P
upgrades: dont have coffee toffee downlink and armor and range upgrade both are 7/10 , all other stuff maxed ..
best so far has been 4 left and noone appearing, i would really like to see 8th level someday ..
1) no real graphic usage yet CPU is very high .. - unoptimized
2) early towers cost too much compared to enemies, later towers are too cheap. - unbalanced
3) sound starts to get on my nerves , rockets are strafing
4) something really weird is going on with game refreshing/repainting
5) hrmm game finished while writing this comment - congrats etc. 50 waves right? how come you dont need to watch last 20 with no real chance of losing ?
you dont need to max the frost tower, range is enough. I usually start with frost tower, put it somewhere in exact centre, max range and then wait for $2500 for golden tower. And then just max it, then next golden and so on. until 10 goldens up or so. only then start upgrading ice again. and then start building flame towers (not upgrading) so they level up a bit for final boss. (some 10 or so is nice enough). Works in hardcore mode (current #3 on hardcore3 yay )
k. 1 frost + gold towers, after 5th upgraded gold tower it was just about spam add gold towers and upgrade as fast as you can , makes it a bit too easy, put some limit there or something (like max 5 gold towers)
targeting system is fine, considering it doesn't matter anyway
to win:
1. build 1 frost tower, upgrade range to somewhere acceptable
2. build 1 gold tower, upgrade range to somewhere ..
3. start upgrading speed of both .. that's pretty much all you need to win
except for boss level .. but by then you should have already upgraded both to max , build several other gold towers and then maybe some more damagedealers (sniper or cannon or poison)
