Glad you liked it!
What kind of missing feedback are you thinking of?

I think a little more camera shake when crashing into other trains would add a nice touch as well as a little more juice when running into other trains on the side. I can see these things happening, but I don't "feel" them happening if that makes sense? I like the red flash when running into the back of a train. I couldn't tell if the red flash happened every time or just when I didn't have enough speed, so I mostly just went off of whether or not my score went up. I think making the two types of rear collisions a little more differentiated visually would help me to gauge whether or not I am going fast enough to score points or just take damage.
There is camera shake when you crash into the back of the trains... it probably is just not enough to really feel it, but I didn't want to go overboard because some people really dislike it (and I def didn't want to spend time making a setting for it)
I agree, some more effects for speeding up would have been nice, but I didn't have time for that.
And the red flash, it only happens when you don't have enough speed. I was way too late at implementing this, so that is all I could do :P
