Thank you so much, really appreciate it :) This was my first 3D game.
I was worried a bit about performance as the last two years' GDTVs I was using onboard graphics, but I finally got a GPU last August. Actually I spent most of last Saturday working on the performance, as hundreds of enemies with all the Unity FPS Microgame components on them did not run well (navmesh agents firing several raycasts every update and other horrors).
An unlimited mode is a great idea. I'm going to add in more fun stuff to try and capture more of the VS magic, like 1) more interesting weapons 2) better passive items 3) all that lovely meta: unlockables and 4) all the missing juice... I haven't got a clue about 3D rendering so the art style might change radically to pixel art (I was going to go down this route initially but had 0 time to do art..!)
Thanks again!
