Just posting a wee update.
I went back to Trawl and changed the sort of "title / on-boarding" screen. It now has a quality control between 1-5 which if you are familiar with Unity is just settings from "crappy looking" to "beautiful". It will also affect the amount of particles we render on your screen.
Hopefully this should help some lower end computers!
p.s. competition coming soon!
