This was pretty fun. While the Resident Evil-style tank controls are kind of frustrating to deal with, they are extremely fitting, and in conjunction with the cooling mechanism, they kind of made me feel like I was responsible for maintaining a machine. :) Good use of the theme; I was continually thinking about the balance between staying active and keeping the mech cool.
The synthesized voice assistant was amusing and thematically appropriate, although it was a little odd that it mispronounced some common words ("resources").
I beat the game a couple of times and didn't realize it--I thought I had lost! A little pop-up would have been helpful.
