Posting the codes in the game chat would be more helpful if the game chat wasn't broken. There has not been anything visible in there for weeks or even months now.
Level 21 takes quite some time, what you need to know is that you have to make words again ('GREEN' of course), but you can't just pick any letter for it. If you click a G and the R you click next causes both the G and R to fall down again it means that wasn't the corresponding R for that G. Click the same G (that just fell down again), and click a different R. If they don't reappear it was a match, and you have to click an E next. If the second E doesn't match they will all fall down again, but in order, so just click the first 3 letters that fall down again and click a different E after that. The first matches will take ages unless you are really lucky, but once a word disappears those letters are gone, so it gets easier over time.
Not saving progress, and for some reason once in a while Chrome decides to scroll down on space instead. Spend about 45 minutes when it scrolled down, registred the mouse click on a recommended game there, and when I got back all progress was lost. Can't be bothered to keep starting over and over again.
What does RFI stand for anyway? NBM I could figure out that it's no base move, but RFI?
I tend to not bother with speed runs either, only when it's a too easy map. Didn't take the win on today's map (9/15) till I had blasters set up to prevent more creepers spawning.
The moment you took some land on Query and Understand move one of the command units there. That way you can use collectors and are not as reliant on guppies.
Seems I talked to the paperboy at the wrong moment. I can only choose between 2 options, and neither gives progress or allows me to leave:
'How's work...' and 'There's too much gossip...'
That's a bug that rarely occurs. I have fixed it for all the other areas, but I didn't touch that one because nobody lamented it until now.
If you reload your game, it should work fine once again
Don't start with broadsword. Don't end with it either. The other two are much easier to play and staff gets overpowered at the end as you don't have to get close to anything anymore and it takes out flyers fast.
For the hard badges: Get the Dart Training Facility to level 3, and do the Clock level for the second hard badge. Placing lots of dart monkeys around the centre in the Armageddon level (many upgraded to 2/3) means cameos are no threat and with 2 darts each they clear the centre well. Get a glue gunner for the dart immunes and level 30 is easy.
For the second hard badge it's important to know that you can actually place monkeys on the path of the balloons in the clock level. Start off by placing the free money at the centre top, and upgrade it as far as possible. Then place a Tack shooter behind it, and waves are a breeze for quite some time. After that it's like all the hard levels, once you get a monkey village with speed and intelligence and get some more towers it's pretty easy.
Took ages to get the hard badge, simply because the plugin would stop responding on the 49th one each time, and after refreshing the last 3 would be there again (rather than just the last one). Even after completing it the last 3 are there again after refreshing. Spikes is the hardest one, as you basically need to do just enough damage with another weapon to make it possible to finish it with the spikes, and half the time (or more) the jumpers will finish it off instead. One try I even had crossbows finish it off when trying spikes, while I had no crossbows deployed at all that round. Not sure what happened there, but that was one of the times the plugin stopped responding soon after.
