Version 0.0.2, a minor update, has been released. Changes (possible spoilers):

• Shows a random tip at the start to help players learn the game.
• Doors are now two tiles wide, to avoid pairs of monsters getting stuck on doors.
• Platformer: better control by implementing "coyote time" and input buffering for jumps (reduces accidental use of the jetpack).
• Boss and lackeys will no longer chase the player out of the boss room (prevents you from being able to cheese the boss by locking him in the doorway).
• Added stats to the end game screen.
• Bugfix: No longer sometimes places two monsters on the same square, causing one of them to fly off due to the collision.
• Balance: reduce gem drop rates (monsters no longer always drop a gem).
• Balance: reduce laser damage from 2 to 1 (to account for the player having fewer gems).
