The questions assume a lot. For example, it assumes that you are in a terrain where a bike would be useful to have with you. But considering you have hooks with you as well, that may not be feasible.
Also, why would I want my clothing in my backpack and not on me?
The click interface is difficult to maneuver, and it's difficult to see the stars at time. Perhaps you should add a color change option for people that seem incapable of seeing the star.
There is an even easier way to beat the game. Just pick a training, and jam the space bar. Eventually, you'll reach level 150. The only thing you'll really lack is energy, but you could buy seed easily after 150 flying.
There appears to be a small problem with the pause menu. When you click "Resume Game," it launches a ball. Seeing as "Resume Game" is in the middle of the screen, I can't aim like this.
I appear to have a weird bug with the character when I move. If I hold the direction key for longer than a second, he starts to stutter step. That is, he looks like I am repeatedly pressing the direction key instead of simply holding it. This isn't too much of a problem when I'm fighting something I don't have to move against, but for bosses, this is really screwing me over.
There is so friction. Watch, put something on a ramp. If it stays, that means there is friction. Problem is, the friction is rather poorly incorperated.
I'm surprised how many people call it a 99 bricks rip off. Honestly, it's more like super stacker.
Other than that, I rather enjoy it. I feel it would be easier if I could freeze objects so I can set up balance before hand, but other than that, it's fine.
