Not sure what everyone else did, because it ran just fine for me.
Also, gonna post the following just in case you're interested in feedback. Pretty sure none of this will be new, but I didn't want to assume either and just keep my mouth shut. If nothing else, take this as a sign someone actually played your demo and was paying attention to it.
Bug Zone:
* Re-entering the main area results in the intro box popping up again. Might wanna set a flag for that wherein if seen set true, if true, don't show again kinda dealio.
* Most notable bug imo is that if the dog pins you while you're down and goes ironically enough for doggy position, it doesn't work correctly. The dog will teleport to the right upon you breaking free, it starts over from ejaculation ending otherwise, and your lust actually slowly goes down, not up, despite being boned repeatedly. Additionally, the animation cycle rapidly tries to finish. Most easily testable by pressing Q near a dog and hoping it doesn't b-line for the crotch lick scene instead.
* Jumping in general needs to be refined. They're barely hops, and jumping while running is like trying to play flappy bird with a stone and a max of two crappy flaps.
* Enemies can grab you (mostly the dogs), even if you're not within range and initiate an H maneuver. I've had moments while jumping on the light fixture wherein I'm teleported down by a dog that's initiated an H maneuver.
* Enemies can grapple you the instant a grapple has ended which is annoying...
* The stamina bar seems to run out a bit too quickly, and sometimes even runs out before it hits full zero. If you've recovered recently and immediately began running and jumping, I've noticed plenty of blue in the bar still but it'll crap out regardless.
* When I punched the caution sign by the pit, it produced multiple objects..?
* I was able to realign a dog by crouch kicking it to the right wherein it's new path was the same but massively to the right. This kind of alignment issue could turn into a game breaking bug, and could really mess stuff up for you later on.
* To mention this more directly, while crawling through a vent, a dog was able to h maneuver my character. While not an outright issue in the long run, that's only if you intend for them to follow you into the vents (which I'm all for). However, in this instance it bugged things out a bit and started a crotch licking maneuver from a crawling maneuver and allowed me to momentarily walk and attack in the crawlspace. Additionally, now there's a floating dead dog in the crawl space.
Suggestion Zone:
* Focus on gameplay first, refine what you have, maybe make just a general test area before defining the map. For the dogs I might suggest the lunging pin be a first entry fix. The pin currently doesn't usually do anything, and instead of initiating a proper tackle to sex animation, b-lines straight for crotch licking when it does work. I'd suggest potentially doubling or at least adding 50% more to the distance of the lunge as well.
* Will it be possible to H maneuver downed enemies?
* Will there be more boob exposure?
* Will the shower ever do anything? If so mind the door to shower "action" hit box or you'll accidentally kick people out.
P.S. Out of curiosity, are you the one doing all the spritework? A part of me was curious to see if I could poke at a sprite or two. I'm not aiming to do much but I'm the sort who likes poking around with other people's sprites and sometimes posting suggestions on spritework as well.
