The game looks incredible. Unfortunately, I haven't fully grasped the game yet.
Where am I supposed to go or what am I supposed to do? I understand it's a maze-like game where you have to find the exit while avoiding aliens, but in the two playthroughs I've played, I've only found one of them, and it's been almost impossible to find the gate to the next level. I also haven't found any items to refill my oxygen, so most of the time it's been a matter of walking aimlessly and waiting to die from lack of oxygen.
On the other hand, I think controlling the camera independently of the character's movement isn't a good decision, since the levels are too dark to be able to search for anything, and it becomes quite confusing to move the character with the mouse while moving the camera with the keyboard.
Even so, it looks like a good game, and I'm sure if you keep developing it, you can make it incredible.
P.S. Sorry for saying so many negative things. I wanted to offer constructive criticism to help you improve the game, but it feels like I'm attacking you. I honestly don't mean to upset you. I enjoyed the game, but I think I can contribute more by giving my honest opinion.
