An interesting idea for the theme.

I didn't really have fun with it though, I think because I didn't feel any sense of being in control. If I had a map, or sign posts, or a compass that pointed to the exit, or some way to judge if I was making progress, then I think this would feel more like "navigating a labyrinth" and less like "20 seconds until game over".

Turning with the keys felt slippery and hard to control. Either using mouse look, or having the camera snap to 90 degree turns when using the keys would have been better choices in my opinion.

Nice lo-fi graphics! Definitely reminds me about the W95 screensaver :-)
There's too much inertia when rotating the player, making it hard to control.

Hm. As already mentioned, too much inertia when turning, it feels like trying your luck for getting the right turn in the labyrinth, and rendering could be improved (it's sort-of slow, I guess there is no effective line-of-sight culling, i.e. portal rendering or the like.

Also, having an "replay" option other than F5 would be neat.

I like the gray goo effect, neatly done!

Needs a "restart" button. At first I tried the "right-hand" rule, but it's hard when you're walking on ice like that. Next I tried assuming that the brighter floor tiles were somehow a hint of the correct direction, it doesn't seem to be the case, but it still put me near the goal of the game and I was able to beat it.

I really like combination of Grey Goo and video game. ;) Simple audio but great atmosphere! Good job.

Nice visuals and audio, definitely good atmosphere. The controls are a bit tough because of the inertia.

The sensitivity is waaat to high. Also clicking on the switch is not very intuitive. I think it should be activated as soon as you touch it or with space, like it was in the old days :D Loved the visuals and I'm glad to see that I wasn't the only one who did an old-school fps thing :)

The turning was a little fast, I was not sure what the killswitch looked like. I enjoyed the sound of the grey goo. I did feel like I was running out of space.

Great concept and that Wins 95/98 feel. Brings me back. Creepy vibes and audio really sets in when I'm frantically looking for a way to save myself. My only issue is the controls; Other than that great job!!

I like the concept, but the controls are frustrating. I ended up using a gamepad thumbstick to reach the end. Clicking the button at the end with the mouse was unexpected. I would prefer the standard WASD + mouse controls that most first person PC games use.
