Yeah the CTRL for jumping is... weird. Has the artist never played an action game before or something?
Z to kick, X to fire a (magic?) shot. Enemies defeated using magic can be "mounted" using C for a temporary bonus to attack or defence.
Scenes and sprites I've found, don't think there's anything else as the demo is pretty short:
Slimes: sprite sex followed by GoR CG when all health lost, can be mounted when stunned
Tentacle plant: Sprite sex (and health damage) if approached normally, no GoR scene, can be mounted when stunned
Purple squirter: Doesn't do anything apart from cover you in goo temporarily, can't be attacked
Not sure what the purpose of the bar under your health is, it seems to go down when you get hit, and recharge slowly, but doesn't seem to affect anything. There's nothing of any use in any of the crates, apart from the occasional heart.
The animations are pretty good, not great, but better than a lot of games. Still looking forward to this, his games tend to be short but have a handful of good scenes.
