To beat level 75, send your jellies to the upper right corner, and from there over to the lab jelly. Keep doing that, and upgrade your lab jelly twice so he can hold more without losing jellies. Once you hit about 270 jellies in the lab, throw them all at the boss. If you're lucky, you'll capture him. From there just mind control with labs and send from the boss to take the rest of the level.
Magnet attraction should be a lot stronger. There's nothing worse than having a huge trail of money following you, only to not get any of it when the magnet wears off.
I'm stuck. I can't move around in the dungeons. The game makes my guy automatically move to the left, and I can't progress. I've tried exiting the browser and getting back in, but I still can't go anywhere.
Best way to win 90% of the levels:
1. Get a few Tecumseh with just 1 upgrade (to see cloaked units).
2. Get a ton of Billy Kid and just upgrade his headshot ability.
Even on the levels with a lot of immune guys, I still had enough Billy Kid to kill them, no problem.
