There are a few problems with all the training mini-games. Fixing these things would make a decent game great. Running: The way the duck runs makes the timing really hard to figure out, sometimes the duck will kind of jump forward and often get you killed. Flying: Not much wrong with it, just the difficulty is a little squewd. Later in the gam the duck moves way too fast and is almost uncontrollable. Swimming: Fun early on but later a bug shows up that makes the duck double jump and fly all over the place, often getting stuck behind something. Climbing: Good concept but there are a few jumps that are almost impossible to make and ocasionally the path will steer off the screen. There are also a few graphical errors throughout the game. These are just my personal opinions though. + if you agree.
