I went with the tight space sine it was noted that this should resemble a mobile game. Maybe I'll change the screen size or make the player unhittable for a short duration after he teleports, thanks for pointing that out!
Regarding the tutorial: I'll keep that in mind when making the next game. I went with this approach since I was tight on time and this was the easiest way for me to explain the mechanics.
And thanks for the compliments!!
