Very well done text/speech system! The pseudo-3d/2d hybrid was pretty neat!
I would recommend making the controls work relative to your view. (I figured out the weird camera controls, but the directions were always relative to the world, not the view.)
Also why did you have meta-game stuff like menu screens be unlocked in the world? That seemed really odd.
Overall, very well done for 48 hours! Like, VERY well done!
Oh I almost forgot to mention, I would recommend super testing your puzzles. Currently it's possible to push the balls into corners such that it's impossible to finish the level.
