I agree, it looks amazing! The only thing is that it feels like turning/twisting the screen is a little slow, i'm not sure how the original game was and if it was also that way there. Otherwise i'm really impressed, great work! It looks beautiful

I played the demo, and let me just say, this already seems better than Matref's attempt at a 3D tunnel game

I just have to ask, though...sometimes, the boards (you know, the black rectangles) look like they have white Xs on them, but they disappear. Not sure what that's about.

One other thing is that, for example, when there's a lot of panels at once coming at you, it's hard to know exactly where they reside spatially. But that's just my opinion. Keep up the great work, I love this game already!

I haven't seen that i had so many answers

That's true, in the real game you can rotate the screen really fast by tilting more your phone but on the calculator getkeys are not adaptative and you just couldn't control your trajectory.

The white cross is the collision detector, it appears on the rectangles that you are going to hit if you don't move.

Yes, Matref's tunnel is in normal speed mode and I think it is a good attempt, it's obvious that no one (That's my opinion but if someone wants to proving I'm false, I'll wait for it  ) can make this kind of game without fullspeed. After all, I've only 70 points and 140 lines calculated on each frame  (+ some rectangles and basic textures).
There is an other thing you must not forget: the tunnel is in 3D but the tunnel trajectory is only in 2D: it only turns left or right.

I noticed something: you don't have invincibility after hitting a beam so you can die really fast in a spiral or if a panel is behind another.

I hope this is the final version 
Changelog:
-A cool menu 
-You are invinsible a little time after hitting an obstacle and the screen is inverted.
-Your score is saved
-The "spider view" inverts the hole program
-An indicator appears when you have 1 or 2 boosts
-The program is now an app
-The Menu disintegration occurs only if there is enough RAM (I don't know exactly how much it takes ~1600 bytes), and it works with everything, it just needs at least 1 pixel on.
