That, or maybe find a Vita TV, though I don't know if it's compatible. It should be, I'm not aware of any touchscreen stuff, though, I'm playing the physical Ps4 version so I wouldn't know for sure. As for a Vita TV, you should check a Toys R Us. Got a second one for my bedroom recently, was the bundle with a controller, memory card & such for only $18. I've also heard of Walmarts having them stupidly cheap.
If it does work on the Vita TV, then you can transfer the save to the cloud I believe?
