Love this developer's games... I am torn about them though..
Great animations, and both games are actual games.. But it's very hit and miss imo.
Some [potentially unnecessary] pro-tips!
Objects and enemies in a stage are randomly placed every time you enter and exit, as well as the Keys in the first zone.
The strung-up women with a bell attached in the second zone also randomly place themselves upon stage load. I don't have an exact count, but, after ringing the bell about 10 or so times, the game will start spawning a "Death" boss that is locked to level 99[?], constantly spawning Deathcube enemies [Of which the levels vary, I only saw level 8 cubes?]. And this Death boss spawns on EVERY new area you enter to, until you enter a safe room to replenish HP.
Ruby's melee combos lock you into the ground, but you can Shoot or Dash out of the recovery anim, so the most optimal damage routing would just be spamming Z-C-Z-C-Z-C-Z-C [Melee-Shoot-Melee-Shoot] until you run out of ammo.
When you Parry, Ruby will turn to face the direction of the attack she parried, so, don't mash your Melee attack to instantly bank in the x5 damage bonus. Parry, wait for the recovery anim to finish, and you'll have about... 3-4ish seconds before the bonus fades. You can parry just about anything that deals damage to you, the only exception to this [I think] is the Ghosts trap in the second zone, and the dildo trap in the first zone.
In lieu of being able to attack mid-air, you can shoot while in the air. Additionally, holding either the Up or Down key will angle your shot appropriately.
If you walk around in a stage and notice a yellow arrow appear above Ruby, but there's nothing noticeable there, throw a flare! It'll [most likely] reveal a chest, and in some areas, secret doors to various goodies.
Not all defeated enemy sex animations are coded equally!! As an example, the Doctors in the second zone recover about 2-3 HP every time you "relieve" yourself with them, while the Vice restores like 10 HP. Don't forget about this mechanic! Having sex with defeated enemies will freeze everyone else in place, so you can, in fact, fuck someone senseless before resuming a fight.
I do sorely wish there were more gang-bang animations... I only saw the Vice have a double penetration animation...
