suggestion to the developer: if you have it programmed so that when dice reach the bottom of the screen they go on endlessly, i'd suggest u kill'em at say x = -20. The same goes for the pills, if u have programmed them to become invisible and become unfunctionable (they can be used only once), i'd suggest again, kill'em after they are used. this can be an easy solution to the lag problem.
if this is not causing lag, however, i'd suggest that u make a restart a REAL restart, so that everything from the last game eating cpu goes down (know what i mean?) If this is the case but u don't know how to solve just sent me a message.
For Challenge 5; just first throw down a oil/ngas well, with 2 NGAS Power Plants. than build 3 metal mines, a land fill, factory, build up 2-3 labs. also, depending on how much food you have, i suggest building 3 farms, on the green slots. it worked for me, its just a pain to have 150 extra energy for it. upgrade trucks for NGAS [3 stars] the N-Gas Plants upgrade 3 stars, and landfill to recycling. Only use the turrets, and build a lot of them around the oil well/ farms/ mines / your little town. By the time it was over i had 500+ metal, 15 garbage trucks 3 engineers, 999+ energy. BANG! Level 5 completed. It make take two or three tries, but you'll get the hang of it. Its really easy the way i did it. Just gotta start off right for it to work.
Four Minute Frenzy
Dude! You just completed the Four Minute Frenzy achievement in Achievement Unlocked and won the Four Minute Frenzy badge and 30 points!
YEAH took me 3 tries
(4 if you take the one before the badges)
narfnin, if you had looked at rudy's page, then you would've found that the new shortcut WILL be 0.
and jackalrama, i find it easier to just pwn everybody with my arrows while upgrading everything i can (except archery mayb)
you should put a dot in the line before Morales were low, in the 2nd or 3d page of the story of the 4th level (when it's about retreating in to the forest and troops decimated and stuff)
