Well I liked the game and played all 9 levels.
There are 2 things that I noticed, you can finish the level even when you die, because dieing results in no gravity and still being able to jump and place Goo.
And sometimes you are stuck on a cliff where you can stand but no longer jump.
I actually liked it so much that I made a video how i played all levels totally how they were not intended to be played.
I only noticed afterwards that I can actually build with these blocks and not have to use them to midair jump LOL.
(nobody saw me fail horribly at level 6 did you?)
