Nice game! It took me multiple tries to realize this:
IMPORTANT: in addition to the controls mentioned in the game, you must also use WASD to move. That was not obvious, and man the game ends quickly without it :)
Once I realized that, the game works and is playable. I love the story, and the slow-typing text bits are really amazing polish for a first game! I only wish the first level were easier, because even after finding WASD, I don't seem able to last more than a few seconds.
(I do wish the shield button was something other than right-click; that causes the browser contextual menu to open for me. Maybe Right Shift or Return would be a better choice?)
