I cannot complete this game :( With auto-regen it is virtually impossible to beat the game with 20% health left because you can't tell what percent you're at and you'll always end up with a % off due to regen :(
I am unable to get the award for clearing a nest with 20% health left. I have slow regen so I've been putting myself down to about 5% before killing the last enemy and 6 times in a row I did not get the award. Do you have to have exactly 20% health? If so, then slow regen makes it pretty much impossible to get the award.
Knife part isn't hard if you take a second to watch and get the timing down. Trying to hit it the first time it passes through the target area will almost always be a miss.
Picross is always good but the controls just weren't there for me. To 'x' a square you should either have had to double-click it or hold shift or something when you clicked instead of having to go to the top and switch back and forth all of the time.
