Seriously, playing this on a touchscreen device would be fantastic. I have an Asus T100, and while technically you
can interact with the game with a touchscreen, it is not really playable.
In particular, a single tap simply repositions the pointer, so to click you need to double-tap everything. At least that should be an easy fix.
Another easy-to-fix, but important changes would be Pause and Menu buttons somewhere on the screen - Pause is central to the gameplay, and it is not available if the keyboard is not connected.
The right-click (press-and-hold) with the touchscreen is too slow, but anyway - I'm pretty sure that by now you've figured it all out (given that the game is being released on the iPad).
So, this post is primarily to assure the developers that touchscreen support on the Windows camp is eagerly waited for. I'd be happy to re-purchase FTL for touchscreen (if my achievements can be ported

)
