Lives!
Have 10 lives at any one time. Collect them from generators and from courses.


Batteries!
Collect 400 batteries. You will probably get them throughout the regular course of the game.

Backups
Once you have activated a backup generator - you will have one backup per attempt of a stage. When lives are depleted use the backup. Do this 20 times.

Boss 5000
Get five of the bosses to 5000 points. This will be very difficult. Just grind each boss until you master it and can hit 5000 points.

Collector
Collect 20 lives from generators. Once you have powered on the generators; they will release lives every so often. These lives do not need to stack - it is all throughout the game.

Meet the ducks
At the very start of the 'Bathtub' stage; there are a group of ducks. Run through them to unlock the achievement.

Long run
Similar to Boss 5000 - but get 6000 points in one boss. Grind the boss you find easiest until you hit 6000 points.

Explorer
Collect all the batteries in the Path stage. This will include exploring all the side paths for all 3 sections of the stage.

Avoid the lights
Don't touch any of the searchlights in the tomb level. I actually unlocked this when I respawned at the checkpoint after the searchlights.

Unscathed
(IN PROGRESS) In theory this should unlock after doing ten courses without crashing. I have done this yet have not unlocked it.

Power UP!
Power up everything in the village. You do not have to collect all the batteries - just get 3 stars in most levels and bosses.

Eaten up!
Crash into the dune worms in the Worms stage 10 times.
