Challenge 6 is possible: you have 10 hits before destroyed, which means you can use 30% of health to quickly splitting and ammo catching (while colliding carelessly) to destroy about half of the orbs.
Nice to create a game for 4-6 years old kids. But the game will be boring quickly, even for them - they will play the original for real challanges. Also too many items per level.
The game was too easy.
but it takes a lot of time to understand how to win a level. but now, after wave number was reduces, people will not fully understand the game, although they will get the badges (except the hard one, which requires to understand the game).
5/5 after all, for unique elements and gameplay in TD (after you though you saw all of them).
none gameplay, no skill as totally random, exhaust cpu, no mute, badly programed, eye aching, badly themed, even the game creator didn't past 10,000.
BOTTOM LINE - REAL 1/5!!!
What happened that Greg suddenly added badges to a 3.5 months old and very poorly made game?
people, stop asking how to get to the secret level, not until level 120, and even after that, if you can't find it, send an email to Pimgd and beg him there
