UberFlight

UberFlight is intense flying game where you score points by flying risky.
The closer (and longer) you fly to the obstacles the more points you get.

Your movement costs energy, and bumping into things costs even more. Keep an eye on your energy-level, because 'out of energy' means 'GAME OVER'.

Levels are procedurally generated, so they're never exactly the same. Memorizing won't help (much), you need to learn to react to situation at hand and make best choice, really fast. A single mistake (probably) won't kill you, but two mistakes in the row will be fatal.

Game has 3 modes :

• arcade — find all required rune-keys to unlock portal to the next world
  
• challenge — play single-world for highest score combo-chain, ranked on leaderboard
  
• zen — no scoring, no damage, just flight of fun and relaxation

Score for every flight earns you some XP, and each level-up gives one upgrade-point.
Those upgrade-point can be spent for number of upgrades and unlockable moves (horizontal and vertical dodge, air-brakes etc).
