Add a SkyTrax tutorial :)

Still needs more parts, and marbles

For the marbles could you add the gold marble from the advent calendar of 2023, and for pieces could you please add the magnetic stick in as well as my own tile the 5 in 1 tile. It’s whatever deadline you want ok?

Things that NEED to be improved in the GraviTrax app

The GraviTrax app is no doubt an amazing game to play, but there are multiple things that has to be improved in the next update.

1. The spiral only has THREE versions of it, and that’s all that you can use. Tsk, tsk. You get one of the versatile GraviTrax elements, and THIS is how you treat it? Shame. The thing you can do to make this better is to make a button in the toolbox (the one that appears when you press/hold a tile or place one) that adjusts the height of the spiral the same way you can adjust the height of a tile. Also, game physics-wise, also make the marble go more faster in the spiral, and by fast, I mean LUDICROUS fast, to put the app spiral more on par with the real thing.

2. The lifter head can be rotated in real life, so I’d suggest you can do the same in the app, and also make the smallest version of the lifter like in reality.

3. The colour swap element needs to be improved because you have to have INSANE speed in the marble to make the marble inside get out, and that’s a bit of a Herculean feat to manage. Oh, and probably remove the part that makes the colour swap just a makeshift version of a tunnel. But then again, it’s fine if it doesn’t get fixed, since the colour swap element is a figment of the GraviTrax community (and mine, as a populist) and doesn’t really exist.

4. The Skytrax spinner doesn’t really have any problems, considering all the Skytrax pieces all came out in the new update (as well as the other quality-of-life improvements) but there’s one failing point. The rotation of the spinner (which is kind of the most important part to note about the spinner) is always just the same one. Maybe be a bit mindful of the other balls dropped? Also, speaking of Skytrax, please put the official Skytrax XXL manual tracks in the next update.

5. Please, please, please, improve where the height tiles are placed when a transparent level is placed, so tracks can be more easier to build by adding a part to select where the height tiles should be placed in the toolbox.

6. This was a huge problem for me when I was playing around with GraviTrax PRO, and that was the placing of the balconies on walls. Now, I haven’t actually experienced GraviTrax PRO in an actual PRO set, so I might be talking wrong, but could you please improve it a bit?

Thanks, hope all this can be improved in the next update!

Pro should be free on mobile

I just am happy this exists, but there is a problem. If people like building pro in real life and they want to recreate their tracks on mobile, THEY HAVE TO PAY $0.99!? Like that’s insane. It also reminds me of
what i learn sometimes from the bad guys 2 movie:Why won’t you give a chance to other people when they don’t have the chance and they need that chance? Everyone needs a chance for stuff such as the title. Please ravensburger give a chance to other people to have pro on mobile. Thanks and no problem. James. S
