I think this was a simple but fun endless runner. I didn't run into any bugs and it controlled quite well for what you were going for. I would have liked to have seen some more background elements (landscape with trees/rocks/buildings/etc) to give it a better sense of speed (which can get pretty fast!) and I think the UI could use some touching up. For example, having the buttons only show up on the android build would be a good thing, as they're too inefficient to use on a PC and just end up cluttering up the view by being there when you don't need them. Pretty fun overall though, well done!

This is my second game and it's good to see that there are no bugs. I was thinking about adding a background but was not able to complete it in time. (my initial thoughts are to instantiate background elements just like the sensitizers and all. Is this right approach?) For UI, I agree with what you suggested.
I am glad to know that the game was fun to play :p. Thanks for playing and giving feedback :)
