I completely missed your post. Thanks I really appreciate it.
You are probably right that it is a bit harder (I am good at the game so have difficulty being objective about this), this wasn't intentional apart from adding a timer.
Is there anything that specifically makes the game such as the timer, spikes, enemies, etc or is it some combination of everything?
I do plan on updating the game (just like last year) to address the bugs (v1.1) and address the difficulty (without redesigning the levels) and a few features I didn't get to originally (v1.2).
