I spent quite some time on the game. Sorry the comment is a bit loose, I'm going to bed right now :).
I had plenty of fun playing the game. It looks and sounds great, the environment is detailed with quite some moving, alien flesh things which move, the atmosphere is very alien and unique and I love it. The game is smooth, snappy and very pleasant to control, the view is unusual but works perfectly, movement feels good, environment is interactive, stunning the enemy feels good, the duration of the stun is right like the overall difficulty of the game and I enjoyed exploring the different sequences.
I did not even realise the game was endless (that explains why I never reached the end while at least on one instance going quite far, crossing several Exit doors) and featured some generation, and now I also wonder if after dying in the same game you get the exact same sequences or not, I think rather yes than no as in the game where I went on several time after dying I never got the plating, for example, and I got it after restarting. There are probably sequences I have not seen but the ones I've seen are varied and overall can be quite interesting as you're chased by an enemy and need to do all the tooth things and such.
When I went far into the dungeon I ended up going out of the bounds of the dungeon (in the air) a couple of time. Besides the only time I got the plating I got it through black doors I could walk through without opening them. Also after I died the life bar did not display properly, it was all black, and after just loading a new game I see it can also happen the first time you load a game too, from dying I am quite confident it is actually functional and it's only a displaying issue. Sometimes when I need to switch to teeth I end up definitely losing the gun. I think the part where you get the boots is a bit weird as I had the impression the lava? there deals no damage regardless of whether you own the boots or not. Finally the position of the enemies is or can get weird, I don't know if it's intended or not but sometimes (always?) an enemy is out of the grid and there's some way to shoot it but you don't really know how. If you think some of these things are wrong then just ignore them, I took some brief notes but clearly did not dig deep and might have totally understood wrong what happened. I realise it's a big list but none of these things really matters, it's a bit confusing at worst.
That's a super cool game, thanks for sharing.
