I like this kind of game. Flappy bird/helicopter game. Simple, nice and straight forward.
One thing that I struggled to accept was the hitbox. It was very very hard to avoid taking damage at level 2 and at level 3 it felt much like pinball :D
I initially thought I'd be training my ghost to become something better. I was attracted by that at first. It's a shame nothing was done with that initial idea. (You still could!)
Thanks for taking me back through memory lane with your submission!
