The game was good, the movement is pretty good just needs a bit of tweaking in the turns. Need to use a lerp function to smooth the turns.
That being said the game really had no point that was easily discernable. It has great potential but there was no score, no killing the other microbes, just running around picking up green spiny looking things.
You have a good start to a game, but you need to have the spiny needles start doing damage to something, and also have something attacking the player.
