Rosenkreuzstilette (ローゼンクロイツスティレッテ) is a platform game published by independent Japanese studio [erka:es]. Gameplay resembles a Mega Man clone, with Spiritia collecting various weapons from each boss defeated, and alternate protagonist Grolla playing more like Zero from the Mega Man X and Mega Man Zero series.
See how many things from different Mega Man games you can spot while watching this! Stage by stage notes are in the author's comments (http://tasvideos.org/4940S.html) .
It is 57.34 seconds faster than the previous run (http://tasvideos.org/2049M.html) by in-game timing parameters, and an improvement of 1087 frames(18.1s) through directly comparable improvements. (Note that the reason why this run appears to be 3s slower than the old run by standard TAS timing parameters is because the published run ends input before the final boss fight whereas this one does not, since doing so is detrimental to in-game time).
