Hey there! Just dropped by to add to the chorus of people saying they can`t move at the beginning - at least, not without some inconveniences.
The problem seems to be with the tutorial - the game freezes whenever one of the instruction screens are supposed to show up. I can unfreeze the game and cause the screen to appear by pressing space or the arrow keys repeatedly, but it is still an inconvenience. Other than that, the game is great! Will be looking forward to more.
