Okay I'm not the biggest fan of being critical but honestly I feel I need to voice it right now as I did hold off voicing some issues that I had with the demo that I for whatever reason thought they would be improved 

I will clarify that I have quite the extensive experience with FPS games, the majority being like this game as in retro and retro style FPS games so I'll run through my issues here 

- Movement speed is ok but a run or auto run would feel better

- I don't know the full list of weapons but a close to mid range weapon like a shotgun would be nice to have as the ones I've used are kinda meh 

- The energy weapon having splash damage (or I believe it has splash damage) is no good and more often got me game overed in hectic fights in the level layouts that tend to be very close quarter

- The health and armour distribution in levels are uneven at times (honestly I kinda understand this one because it's a pain at times to figure something like that out when I build levels in Doom Builder, so finding that middle ground between challenge and fairness is tricky considering difficulty levels and player skill)

- The wind up on the chaingun is kinda unnecessary I feel, either remove it or half the wind up so it's more on demand firepower rather than having to wait a minute 

I think that is all I have currently in terms of feedback as I don't have anything else on mind besides the forementioned, there is a minor one where I find the energy weapons sprite to be kinda flat and not really have that angled down the barrel perspective which I find a little jarring but the major issues are probably more so a issue than that

Anyways I apologise if this comes off a little rant-y or overly negative but I felt I should at least mention it, I'll continue to play the game and see if I feel a little different about some things and see more of what the game has in the later levels 

So yeah thanks for your time and I wish you the best   

I'm glad the update is bringing more content. I've played through the game and $15 felt a little pricey for what I got out of it (felt more like an $8-$10 game). I'm hoping the extra content will make the $15 tag worth it, but I'll have to wait a few months to find out.

Personally, I'm hoping to see more Breast Expansion content, particularly since the demo didn't feature any. (Something you should probably explain on certain other sites the game is being advertised on. The demo is tagged fine here.)

I saw the stairs mentioned in another comment, so I won't reiterate on those. I do think more could be done to indicate the thresholds for the level bonuses in the main menu. I had little reason to use more than the pistol in most cases, with the other cases being defaulted to the Jupiter Cannon. The Minigun didn't really fire fast enough to seem worth using over the pistol. The Glue Gun felt like it was essentially a melee with extra range.

Two major annoyances I wanted to bring up. The mostly invisible enemies are... They feel kind of uncalled for. Once you know they're there, they are less of an issue. But it's still a gut punch that isn't fun to deal with. I think they and the scientists should be excluded from the spawn list in the boss level. I get why spawns need to happen there, but the invisibility and how scientists attack are both quite annoying on top of everything else that happens.
