It's very rare that I find a H-game that makes me give a damn about the story line. This was accomplished beautifully here. The hit boxes were really on point, the platforming with the vents were a nice challenge for getting the timing of the jumps down to reach some of the data banks.
The ambient soundtrack was also a nice touch as well.
Though while on the topic of the jumps, i did notice there was a bit of response lag while trying to jump with a charged shot ready. It was kinda irritating trying to jump and hit the winged enemies when the jump key was spotty while I had a charged blast ready.
Other than that I genuinely enjoyed this and would love to see how this gets expanded upon.
