Cool small game.
It is simple, but it doesn't really matter - I enjoyed that compressed story with fun ending.
Maze made absolute sense to me, it was almost like a metaphor for scientists searching for antidote - you have to explore dead ends to find the correct one.
I loved the idea of shrinking vision as poison indicator - so clever.
Movement binded to arrow keys instead to WASD throw me back to 90s. :-)
And don't be so harsh on yourself, for such a small time this is awesome result!
