Note: I'm running the supporter version 0.27
The game's great, I've played through it a few times and keep coming back to the phantoms for more. It's an interesting concept and solid execution; I've only encountered 1 bug so far (details below - point 2) and I also like the inclusioon of the little lore notes. Gets me more involved in the story than I ever expected to be, which is cool. I do still have some comments/concerns though, so here we are.
1. The base run speed. I understand needing shoes to run faster as a mechanic, but the base walking/running speed with or without shoes feels kind of slow for how big the maps are.
2. Shooting controls. I understand this is meant to be kind of a hentai survival horror, so poor controls might be intentional to a certain degree, but I personally still find combat frustrating to the point that I stealthed all the way through the game instead, shooting only when I absolutely had to (like for the mantis). On the note of combat, I ran into a weird issue with the mantis fight once after using the "after scientist" skip where halfway during the boss fight, the girl npc stopped giving me ammo. I came into the fight with about 12 shots, she gave me 2 reloads and then just... stopped. I ended up running around in circles for 5 minutes before giving up and restarting the fight with cheat engine. Adding infinite ammo to cheat mode, as mentioned earlier in the thread, would also be welcome.
3. Escaping. The system of spending your "health" essentially to break free from grabs is interesting and fresh, but having to save enough to stand up afterwards can be frustrating when there are multiple enemies present, not to mention the regen is painfully slow even at the best of times. ALSO, this is a lesser complaint but I feel like if cheat mode lets you use infinite heals, you should be able to use them to restore current stamina, even when you aren't missing any max. Maybe increase the regen speed, or reduce the cooldown timer between escape attempts, or make the resist guage build up faster, or honestly any combination of the three would be very welcome. The system is currently more tedious than it needs to be, but I like the potential.
4. This is less of a constructive criticism and more of a personal thing, but I think the scenes could use some more variety (and more group activity, specifically.) So far, every single enemy except the phantoms goes 1 at a time and uses her vag; I would love to see some fellatio or anal mixed in, and I would kill for more gangbangs like with the phantoms (hands down the best enemy by the way, both their animations are great.) I got really excited when I saw the facehuggers, especially when I saw multiple together, but was disappointed to see no actual facehugging or enemy stacking (it would be so easy for a second one to latch onto her face while the first is already fucking her.) Also kind of holding out hope that there will be a wider variety of pregnancies in the future, getting a bit tired of seeing the same giant worm every time. Especially since the worm knocks me up with another worm quite frequently.
5. This is a collection of small ui/control optimizations I'd like to point out/ask for, such as pressing esc with your inventory inventory closing it instead of opening the pause menu over top, or having an honest-to-god restart button so I don't have to close the game down and reopen it every time something goes wrong. It would be nice if you could reload your "gun" without emptying the entire magazine, but I can understand if that was done purposefully to fit the survival horror theme. I don't expect this for the main game, but I hope any future gallery has a free camera option. Having the camera locked onto a specific "center" point of the scene can sometimes make it hard to see what's going on unless you search around with the mouse. This is especially egregious when you get knocked into a wall or door and the camera struggles with clipping issues. A skip option for animations that won't kill you, but you can't escape from would be nice. I liked the birth & subsequent rape by worm the first couple times, but after that I'd rather just get it over with and keep playing.
6. I understand that a gallery is coming in a future update, but I just wanted to mention the game needs one; enemies/scenes that you can't go back to, the skip system only having a couple very distant options and only having one active save slot at a time make it tedious and difficult to go for one specific scene unless it's right near a skip point.
This might sound overly negative and I'm sorry if it comes across that way - but I do really like this game. I hope everything keeps going well with development and I'm really looking forward to more.
