Thanks a lot for the positive feedback, guys!
haha such a nice idea. i see that you figured out that you can just mirror tricks to get them with the other foot :-D
to improve it, maybe you could add a foot to start with, and according to a discussion here earlier, it would be consistent ending tatw / matw etc with the same foot as the "cross" touch.
Maybe the combo could be more fluent if there was no black image in between, and maybe some short overlap as a transition between two tricks?
But great work so far, really cool app!
Yeah, I have those things in mind. I'm gonna allow cross-tricks to end with both feet. Limiting it to only end with the same foot as the cross, combos like amatw-amatw turn out kinda strange...
I haven't been able to do anything about the black gap between tricks. It's just how transitions between videos behave in Android versions below 4.0. If you have 4.0 or above there shouldn't be a black gap, although there might be some exceptions. I don't get black gaps on my Android 4.0.3 tablet, while I do on my 2.3.5 phone.
And yeah, I had to mirror latw and alatw because I can't do them with weak foot =P
Really nice, but nt doesn't work, still nice job 
I realize I should have added an explanation to how the nt works. Check the nt-box and then press the tricks that are gonna be nt and then uncheck the nt-box. You will see "nt" gets added after the tricks and there are no "-" between them. As for playing nt-combos I haven't implemented that yet.
A new update is coming soon, where beck atw, magellan, ahtatw and ahmatw are some of the tricks that will be added!
