Okay, instead of whining about how much of a grindfest this game is I've decided to help you all beat it as quickly as possible!
[DUCKLIFE 4 QUICK-GRIND GUIDE]
---RUNNING TRAINING---
Skip the first challenge by standing still and insta-losing, the 2nd and 3rd ones give you more levels/time spent.
---SWIMMING TRAINING---
Skip the 1st and 2nd challenges by getting killed. The diving challenge gives you levels way faster!
---FLYING TRAINING---
End the 1st and 2nd challenge ASAP and go straight to the cannon challenge. Try to place your mouse in a spot you know will be a hit!
---CLIMBING TRAINING---
The 2nd challenge (Risk) is the fastest way to grind climbing levels. TIP: If the warning triangle appears while you have a VISIBLE hole beneath you it means you won't make it to the next hole, and should try to go down to the hole you can see.
---JUMPING TRAINING---
Get yourself crushed as fast as you can in the 1st challenge, you will want to use your time getting high scores on 2 and 3.
AI can easily be crippled early on by sending out an elk cloner in each line, thus forcing it to build cannons. You can also make the AI replace its $ towers by sending in a large amount of malwares at once! Vote this comment up to keep it visible
"So, Chief, we finally caught that homicidal bison! What should we do with him?" "Put him back in the ring with the now incapacitated Jawbreaker! He won't escape this time!!!"
