once you beat the final boss getting to wave 25 is very easy.... just get 4 lasers three with homing and splitting and one with homing and weaken. heck i used that combo to beat the final boss as well. you should have no need to use a bomb even when you're up to wave 30+, final boss though i would recommend using the hp drain bomb.
there's a glitch where if you play long enough the number displaying the tech points get bigger and bigger and eventually it covers the whole screen and you can't press on the tiles or pick your opponent -_- probably forgot to clear the size?
here is a neat glitch to all those who find this hard. make a character then name it. when you reach the final boss (if you can not kill him) quit the game (but have it saved) then make new game but this time pick the same class and name the guy the same as the first one. you should start with all the skills,money and equips as your first file and now you can do all the missions again for money and xp. hope this helps =D
AMAZING! simply amazing! this game was one of the best games i have played in a LONG time! caps off to whoever made this game. and i loved the ending though i'm not sure what happened between him and his mom =P
a tip for those that want to beat wave 25. first set up 4 pierce blocks in front of the toys then place a attack booster at the top. do this again but put it in front of the monster portals and make it face the other blocks. then put one slow block and one invis block in the middle next to each other. then just save up your souls and whack away! if your towers get turned to cheese pause time and rebuild it. ALWAYS rebuild as soon as one turns to cheese. this method only works if there is no invis monsters in the beginning. by the end is not a lot of your towers were turned to cheese you should have around 250-300+ souls and that will let you hit around 30+ with a sword swing. i have tried this strategy a lot of times and it always works.
