Oh no, I actually love it. My game has the exactly same shader you use, and it honestly would look fantastic on the Vita.
Problem is that with the way I do the ports, shaders cannot be ported easily, and the CRT shader is too heavy on Vita's GPU

I had to code in gamepad support and a reset button, but other than that it was pretty straightforward
That was fast :D You're doing great work, makes me very happy to see more DLs on any platform
So I'm curious about your process a bit. Seems like avoiding heavy shaders, having gamepad input, and not using much text drawing makes for easier ports - so what do you do if you want to port something that relies on a lot of text like an RPG?
Avoiding heavy shaders like CRT is kinda of a requirement, but overall there's no way to port GMS 2 shaders yet (Working on that), so even if the Vita could handle the CRT shader perfectly, I don't have a way to port it at all.
Text is never a problem. The only game that gave me problems is Warlord, but it's due to a text parsing issue. It converts the newlines to an square and it doesn't, you know, break the line. I find this rather strange and I'm not really sure why it's happening at all.
