what makes this game easy, is that u practicaly cant die, ur shield regenerates way too fast and if u upgrade, it, ur almost invisible (with lvl 1 shield, u can survive a yellow's orb continuous attack without losing any hp)
great game, but most levels after 50 have objects, that u know what u are seeing but dont know the word for it, or you look an object that doesnt at all look like the answer to you :/
still, awesome idea for a puzzle game. I always wanted to see a 1d game xD
if u want to get really high scores (much higher than the glowing frame score), gem bombs is the best solution - u can release 5 waves at once and defeat them with the massive splash damage from the bombs (even grade 1)
bosses are a bit of a pain then but even they often fall down to the mighty gem bombs
the gem bomb thingy ruins the aspect of a TD though :/
a tip for the first epic boss - dont go for too many weak gems on towers or 1 grade 19854 gem on a tower. 6 gems of grade 5-6 should do it. also try to keep them pure for better special effects. Build lots of water trenches. when you feel you got a good defense, get lots of gems and throw them at monsters so you get extra points at the end. If the boss leaks past your gems, use them as bombs.
btw this game isnt made for badges, sure people want points... well for me, badges ruined the game as now i try to make as much points as possible so i dont enjoy the game...
