You progress faster in this game than in C.A.T.S., and there's no annoying ads (somehow). The best part about this app that sets it apart from similarly constructed games is that clan creation comes at no cost!
This game reminds me of the original LEGO Racers, which I still play to this day! (This makes me feel old, which gives it the essence of nostalgia!)
There are a few minor tweaks that this game's UI DESPERATELY NEEDS!!!
Many games have the layout across the bottom of the screen in the order of "left, right; backward, accelerate," but my phone encounters an issue often whereby ALL FOUR of these controls FAIL more than they trigger, because I end up applying too much pressure on the screen and weakening the sensor (except that section of the screen works perfectly well in apps designed by Apple). Imagine your brakes failing in real life. That's equivalent to the accelerator failing in a demolition derby. This does not happen to this app alone, which leads me to think something is wrong with basic movement controls on a wide scale. I suggest that there be an "controls setup" feature that allows users to optimize where each control is positioned on the screen.
Two things about the builder:
1. I cannot adjust the camera angle low enough to attach items to the bottom of a suspended object. It is fixed at 90°.
2. For the 2x2x1.5 diagonal pieces (and any piece that has 1completely flat side, for that matter), it is very annoying that I cannot attach items to their sides. I don't play Minecraft, so I don't know if that function is absent for a reason...
The last problem (and this is HUGE) is that if anything interrupts a battle, you automatically disconnect and cannot return. The only ways I see to get around this are to turn off cellular data (not doable offline, and bad if some without an iPhone needs to text you or anybody needs to call), have a wristwatch handy to keep an eye on the time, and make sure nothing at all is going to demand your attention for at most 290 seconds.
Fix this by adding an auto-pause feature when play is interrupted instead of instant disqualification, and there should be an in-game clock on the pause menu, as well as a 'continue' button. (Currently the only option is 'End game.')
I really want to rate this well, since it is mostly bug-free and ad-free (could be something in Screen Time, but that hasn't stopped other apps...)
EDIT: I tried deleting and reinstalling the app to see if that helped. All progress was lost. I am deleting it again now until that gets fixed. Literally all other games I have played recognize me when I reinstall, but this is too good to withstand an exception.
