I made it to the portal! There's alot to like here. The Alien Isolation style gameplay was great, the graphics are right up my alley, the abandon spaceship with ladders and vents to traverse was a nice touch, movement was well implemented. The flashlight didn't seem to have much use but it still helped add to the darker parts of the ship.
Only thing I wish there was sound an music, even basic public domain stuff can go a really long way to add to the ambience. There's not a lot of feedback when the monster kills someone, I wish there was more to that mechanic as I just felt I would randomly cross by the monster and one of my people would go away, but only sometimes. This could be fleshed out to be more engaging.
Overall great job! I would like to see this developed more,
