Hi Josh,
thank you for buying Assault Wave. Sorry to hear you’re having trouble.
If you have iPad 1, we recommend you close all other open applications before playing, as that has an effect on memory usage.
In the next update (1.1) going live in couple of days, at least campaign crash bug has been fixed: the bug was when you played a battle in the campaign and won, if the game crashed before the summary screen, the result was not saved. After the update, if the game crashes, the end result is saved, and when you continue the campaign you are taken to the next battle.
The design of the user interface in intentionally simple and easy to use. If you’re interested to read a preview that presents some of the tactical choices you have in the game, I’d recommend one from Armchair General:

In single player campaigns, and in the Online multiplayer, you gradually unlock more Units and Commands.
In total there are currently 13 different Units and 9 different Commands. A bit later on well release an update that adds 4 Units to the multiplayer (both Online, and On Same Device).
In game the tactical choices come e.g. from which Units you send out for the objectives like conquering a Victory Location that generates Battle Points that you need in order to win, or collecting a Collectable from the battle field, and naturally what units to use against what enemy units.
Also the terrain has an effect: if your unit is in a forest, ruins or bocage, it gains some protection against incoming fire.
I’d recommend giving the On Same Device multiplayer a go with a friend, or trying out the Online multiplayer, might be you’d like those :)
