After furiously fighting my way through an old Martian temple, I found myself at the level boss with no lives in reserve and no back-up credits. That means I'll die to a single hit. And I've never fought this boss before, meaning I have no clue what his attack patterns look like. I resign myself to dying horribly.
After some amazing dodges, lots of bullets and a few perfectly-timed Vaunts, I watched in amazement as the boss began to explode. I'd beaten him without a single hit! I was ecstatic!
...and then the boss was re-announced as the game's final boss, his health bar was refilled, and I was killed by a laser beam. 
Jamestown. I guess I should've expected something like that to happen, given that the development studio behind this game are called "Final Form Games"

That stage is HARD D:
Trying a speed run in Spelunkey. I run past some spikes, leap over a small hill, get nailed by an arrow trap, and fly back to land dead-center on previously-mentioned spikes. Insta-death. I swear this game is telepathic, as it always throws the most bs-y obstacles at me when I try to complete a speed run.
