First i like to say that i really like your game and i'm just give my two sense in what i would like to see changed to help your game. You do not have to listen to anything that i'm about to write as it is your game and don't owe us anything at all.
Now I tried 4 stages so far and stage 1 was fine but after that it was really hard to do anything after like round 5 either due to the orcs blow darts/traps, the really small maggots/fly bullshit or the metroids like/ fast as fuck dudes that can down you in 4 hits plus the face hugger that i tried to find a way to get off me for like 10 mins before just being over run by everything else. Also when you mind broke and restart in the bunker let us get out of bed quicker as having to wait about 15 seconds every restart is a bit annoying.
I think that having some armor/ more HP/ being able to get enemies off you quicker/ maybe take away STR all together, should be the first things to fix because i don't know about you but most people just can't spam the buttons that quickly without like 30% of your STR. gone after 1 guy and after the first 30% is gone it like 40% the next time which you fuck after that no matter what.
The perks were fine with like maybe a 33% quicker reload perk/ maybe a perk that makes getting out of grabs faster/ a perk that doubles your dodging stamina. Also maybe a place-able turret or something that you have to buy ammo for then run to it to reload it that takes a few seconds. Maybe change the 15 second invincible drug to not stun you as well. As well as a item that restores you STR. and maybe have all items be in the store instead of random each round because RNG can fuck you sometimes. Maybe a item that restores 1 heart that cost a lot so it can't be spam bought. Also maybe being able to upgrade a weapon's power for like double what it cost or something. Also have the shops be a bit closer as it can be hard to get to both on the larger maps in 30 seconds or change the 30 seconds to like 60 seconds instead since we can skip to the next round.
Most of the weapons felt a bit weak after like round 10 unless you had the 50% damage perk with shotguns really fucking you due some being really slow to reload plus the enemies just being all over the place. The 250 round LMG was the best gun for everything which is fine since it cost $3000 but the 50 round LMG should be a bit more powerful if it going to be the same price. The starter pistol is fine for the first stage but really didn't do much in any other stage due to the enemies being able to quickly spam attack you from all angles so maybe make the enemies a little easier to kill for the first 3 rounds/ slightly buff the starter pistol. The flamethrower on stage 4 is nice but the range is a bit short for it to help with the stun attack from the metroids like enemy that can shoot from far away.
Now most of the enemies are fine but maybe make it so that the harder enemies don't spawn in till some rounds have pass or have a enemy introduced every few rounds to give the player some time to get cash and buy some equipment. Now i don't like how the later enemies can just make you drop your equipment in some of their grabs instead just let the player keep it as the active item at the time because it's annoying to have to pick it up in the middle of a fight then quickly switch back to it while dodging everything else only to get grab again and lose it once more. Also have a button to skip the much longer sex scenes if you can't escape at the cost of 1 heart or something as some people will want to get back to the fight then have to wait every time. Also make the invincible frames after the sex a little longer so you can get up better.
In conclusion I want to thank you for all the hard work that you put in this game and hope that you continue to do well in anything you do in the future. Have a good day. :)
