I had to retry "Timing is everything" about 7 times, before I took 5 and the pace seemed changed when I returned.
The graphics are of a consistent theme (good even, considering you were on programmer duty), and animated very well. These make for a solid game. And I can't usually stand platformers!
I didn't really get the ending, other than there were no more trap doors. Nor did I find any of the words from each level, other than the printed text at the starts.
