I was also glad to discover this was being made into a larger game! I stumbled onto Pico8 through the PocketCHIP, and then got horribly addicted to ToA. I'm also hoping this makes it's way to Android eventually, as it would be an excellent touch-based game. In the mean time, I'm happy to confirm that it works great on a HP Stream 7 (got one of those tablets cheap a year or so ago) running Windows 10. Looks great when run at full screen. (Specs on the device, which runs at 1280x800 : http://www.cnet.com/products/hp-stream-7-5709-tabl...)
There's one thing that would help touch controls a little -- if there was an option to set a double-tap to kill monsters instead of the default single one. With touch the only way to get info on a selected monster group right now is to "right-click", or tap and hold. Maybe it's just a personal preference, but I think it would work better if it was a single tap to select and a double to clear. With a mouse (and hover), it makes sense to keep it as is, but touch has a different feel.
Thanks so much for developing this game! I'm also a fan of Stray Shot and Underworld Siege, among others. Would love to see some of those get developed further too!
