starting a level with at least one angel doll accessory basically guarantees a gold medal. restart each level until you have one (two is better). just be sure to put it/them on the tower/s that will be scoring the most kills
PASS IT ON: you only need to complete the 15 levels ONCE. the badges/card won't be given immediately, but they WILL show up if you give it enough time. if you are paranoid, take a screenshot, and submit a missing badge/challenge
does anybody know what the "new ability" is that is unlocked after 60 achievments? i have well over 60, and have not noticed anything new... for the developer: name and describe the new powerups/abilities that are unlocked either on the instruction screen or when they are unlocked.
is it even possible to die within 10 seconds of starting a game? the invincible period after you get hit makes this WAY harder than it seems. anybody got any hints?
some ways to get more points: use "angel doll" accessory (double points for kills), send waves early, longer waves (use skill points), get extra lives (also done with skill points)
anyone who can't pass lvl1: look at the WHOLE map, not just the visible screen you start with. see the place where 4 paths converge? place your units there.
INCLUDE THIS IN THE INSTRUCTIONS!You can add blocks in the middle of an already existing stack... just click where you want the new block to go, and the old ones above it will move up.
