Nice game, I like 1st person puzzle games like this. However, could not go very far in the game, it seems it have some bugs. 1st bug was on the room with two round spinning blades on the floor, where you have to cut the block in half. The piece you leave in the wall that goes up (that has a switch on it to open the door) disappears when the walls go up. Then it will either reappear, or disappear completely then you are forced to restart the game. If you can get past that, the next bug was in the 1st room that has a moving laser grid and acid pool, I died there and when I respawned I was under the floor and falling into endless white, then the game froze and I Was forced to force quit.
Interesting. None of our testers reported anything like this. I think I know what this is - both of those issues must be related to level streaming, as our level segments are loaded in and out of memory dynamically which is error-prone on slower systems. We can most likely patch these issues out relatively easily.
Anyway, sorry you had a poor experience! Lesson learned there.
