I currently study computer science at Technical University of Darmstadt with focus on machine learning, computer vision and robotics.
A nice idea and game, but there are severall things I don't reall like:
-Unskippable (long) intro/logos etc.
-FoV too low
-Pretty hard for easy (in my point of view!)
-Resolution is buggy/too large for FullHD
-Not really a conclusive (upgrade) menu (e.g. equipping sentrys? oO)
-Waves starting too early
But there are some things I like:
+Nice train idea
+Lovely art style
+/- Sounds are ok
+Existing weapons are nice
Just some thoughts about the game, I know this is made by students in a universaty and therefore I really have to say that this is a great work! I don't know how long they had time to create this, therefore it is a nice result.

Thats how a pistol should shoot! xD
