The gameplay itself is solid, the UI is clear, and I didn't find any bugs during the entire time I played, so you've done a thorough work there.
I didn't really like the graphical style because the it was all white/gray/black. I know it was suggested that you use an art style like this, but I personally don't like it. It's actually one of the reasons why I don't like Limbo either.
At times, I felt it was sometimes impossible to hit all the cats/people. For example, there was once a star that I had to jump to to get it, but then I couldn't jump again fast enough to reach a floating cat.
Btw, will you add an endless mode where you're just trying to get the biggest high score? I personally like doing the tasks more though, since I've never been a fan of high score games. I just thought some players might like a mode like this.
Thanks for the feedback!
I do plan on keeping the art style, since the game is so far along. I plan to try to make the art style much different in my next game, however, art has never been one of my strengths.
I've have been trying to work more on the level generation, so that each level is fair and can be "solved". But you are right at times the game creates levels that make it impossible to complete the task. Still needs work.
I have been thinking about an endless run mode, and with your feedback I will definitely put it in now.
