Well, I came back to it, and got a clear, in 1:50. That doesn't count a bunch of deaths and runbacks. 960HP, 212MP, and these majors (rot13'd): pbzcnff, nezbe, obbgf, ohefg fubg, oybpx fpnaare, pynjf. I wonder what major upgrades are that I missed...? I'm guessing one lets you "shoot down" somehow, there are a couple of mysteries I never figured out that seem to require that.
I'd be interested in seeing a map of the game world...I didn't make one myself. The area with the lava especially, I found myself taking a long backtrack that I'm not sure was required. Glad I found both items in that area, though! The final section would have been extremely painful without them.
I feel like the movement tech is in a bit of a weird place...it's extremely dangerous to use the slide and divekick in most rooms, especially since enemy damage is quite high compared to the health they drop. I can believe that a speedrunner might be able to make good use of them, but as a person of merely average-to-decent skill, I tried to use them a few times, got punished, and then ignored them except when obviously relevant.
Thank you for sharing your game with us :)
