Difficulty spikes at the start and end. Once I'd finally made it through the last tunnel as I'd almost run out of energy, I noticed a lag spike. Thought nothing of it. Landed on roof.
It was at this moment with the final reward I thought I was done but the truth is that BLOOD ENERGY doesn't stand for BLOOD ENERGY. It stands for MB of RAM that the game is using.
My computer had a stroke.
10/10 cute girl though
The facial expressions to determine if it's safe to land are cute but it's a bit hard to judge compared to something a meter with a safe speed marked. If the game was longer you'd probably get used to it.
