This game needs more visual feedback. The effect of colliding with obstacles is only visible if you keep an eye on the energy bar, there is no real visual feedback to indicate if something is harmful or beneficial to the player.
The obstacles also start spawning too soon. I just started a new level, and already hit a randomly spawned obstacle because it was right next to my character. There should be some buffer zone at the start before they start being spawned.
The character's movement is tediously slow. Not at all what I expected with these hyperspace visuals.
And finally, the energy- It just keeps running out, and I have not found a way to refill it. I thought the yellow and green obstacles that looked like batteries might recover it, but they only took away from it.
If some rare pick-up-ables recover it, then the game is just too reliant on luck.
