The words "You lose" displayed on the screen is very misleading to convince the player that it is game over...before pressing anything. And when you lose for real, there is no restart button so the whole clip has to reload again. It is possible to survive (but there is no point since the gameplay will be infinite until you die), but the design of the game makes it impossible for the player to have the patience to play each time after he dies. There is no point to tell the player he wins at the very end even when he know he lost. Must as well make the actual gameplay more challenging, add in a score system and variety of enemies to make it decent to play.
