when I saw the robogrannies, all i could see was the vacuum from the teletubbies

I thought this was a great little game 

Great voice acting, I liked that they had a lot of different possible lines to say and it wasn't just one thing repeated. It gave me 90s vibes right away when I looked out into space, which reminded me of Duke Nukem 3D, there was a level with SpaceWindows like that. I did get spooked by a RoboGrandma at one point. I went into a room and one was right there, which made me audibly gasp, so good job! This has room for expansion. Maybe, in addition to cookies, you could collect some kind of alien-sweet, then trade them to some alien who stays at your ship, and he gives you weapons or upgrades or something in exchange. And if you added more levels, there could be more advanced types of RoboGrandmas, and each different type would have their own dialogue. Maybe there could be a RoboGrandmaCopter or a RoboGrandmaTank.

I like the concept here! The graphics are very 90s. I really like the HUD design, with the light indicator in the center and how it looks like part of a helmet. The voice acting for Robogranny is also well done. I especially like how there are alternate versions of some voice lines where the voice sounds more corrupted/glitched, kind of like Shodan from System Shock.

It's cool that you can be spotted through both light and sound, and that different surfaces produce more or less sound. There are many possibilities with these mechanics.

It's awesome that you added a save and load system. I imagine that couldn't have been too easy.

 I do have some ideas on how the game could be improved, as well as some bugs I'd like to mention.

I think one of my main complaints about the game is that Robogranny's artificial intelligence could use some improvement. She doesn't seem to have any path finding, so if she hears you from another room, or around a corner, she can't really do anything.  This makes it very easy to get away from her if you're being chased.

There were a couple times where the game crashed out of nowhere. I'm not sure why this happened.  I played the windows version.

There were a few objects in the level that had no collision and I could just walk right through them. The vent you can go through is cool, but it's difficult to get inside it. Also, climbing the boxes to get to the vent can be finicky, since the climbing animation doesn't always trigger, or at least it's not clear how to trigger it.

Some more sound effects for actions like picking up cookies, opening doors, and trying to open locked doors would really help a lot. Sound effects can make even the smallest of actions more satisfying and help the player fully understand what's happening in the game.

This game's got a lot of potential! Keep up the good work!

I was not prepared for Robogranny to be so unnerving!

The core gameplay loop is great - being introduced to the single Robogranny in a corridor where she's easy to avoid lulled me into a false sense of security, before moving on to more challenging areas. 

The Robogrannys themselves are fantastic, with a charmingly goofy looking model that still managed to jumpscare me multiple times when they were waiting for me behind a door. The voice clips in particular are just wonderful, and added so much character :)

The run mechanic felt a little underutilised - I loved the idea of using it increasing my risk of detection, but as it didn't add much speed I mostly just avoided using it when in dangerous areas. It's a really cool concept though, I'd love to see it iterated on.

The 90s style is perfect. The carpet reminded me of the original Thief, and I very much want to eat one of those wonderful low-poly cookies!
