Elasto Mania is indeed closer to lunar gravity than earth's. I remember some guys calculated it to around 1-2m/s². Anyway, the main differences in this game compared to Elasto Mania are, not taking extra features into consideration:

• Accelerating in the air doesn't cause angular momentum.
• The head is dead centered. There is no difference if you turn the head to avoid obstacles.
• The breaks have little to no grip.
• Missing faster spin. (Alovolt)
• Great angular momentum can be cancelled out with one spin in the opposite direction.
