Game is just about the right length, short and sweet without getting too tedious. I would appreciate a level counter, perhaps, though that might break the fluidity of the levels. One gripe I have is the levels all seem to be arbitary; there is no sense of progress, rather just separate rooms connected to one another. The time counter tends to discourage exploration of the levels; I never knew what the bubble-panel did until late in the game. All in all, a fun game.
It's a terrible game, honestly... Technically, the game is fine, but the lack of any progress or any scoring system OR enemies (two enemies, what?) makes this game a real bore.
Pressing the space key down and not moving will guarantee you an unloseable game. To counter this, add a shooting ship or widen the hitbox of the player's ship. 2/5
