Cool game - some annoyances

Edit edit (plus one star): I finally figured out how to rearrange my mechs. I still have no idea how to "craft" items or what that means - there essentially is no user guide. Theres something that talks about weapons a little bit, and a wiki with almost nothing on it. Id still like to be able to select a mech to start with on each mission, and to be able to go through my entire stable, if necessary to complete a mission.

Edit (plus one star): Now I can buy stuff - I had to uninstall and reinstall the game, but the game hangs and drops connections all the time. Also, as far as I can tell, theres no way to change the order of your mechs without completely dismantling and rebuilding them in the new order. You should be able to choose your mech before each mission. You should also be able to use up all your mechs on a mission instead of just resurrecting the one in first position if it gets destroyed.

Kind of a fun game, but in app purchasing doesnt work. I was going to buy the intro package, but, when I go to purchase the red things and tap on one of the packages, nothing happens.
