Thanks for the great feedback! I agree with your comment about finding objects - I have already addressed this in the updated version of the game that I will upload post-jam, in which all interactable objects have an outline. There is a flashlight though already when you press F ;)
I might experiment with adding a mini-map back in - maybe a more basic one than the way the controller did it - as I don't want people to get lost so much as feel uncertain as to what is around the next corner. From other feedback I think that I might have gone a bit too far with "jump-scares", so will be working on a way to reduce that a bit and instead increase apprehension.
Gun-wise, to be honest I couldn't think of a better way to do it in the time available - I might swap out the sounds and make them more like blasters than everyday gun sounds...
The story is definitely not fully implemented yet - the final boss was supposed to be some sort of weaponised mech that the ships computer had constructed. I want to add more story elements to the game, like having dialog between the player and the computer. I might even extend it so that the player could maybe try and fix the computer before having to give up and evacuate the ship... not sure yet!
