Hi there! Here are some comments about your game!
-body temp doesnt reset when resetting from game over
-teach me how to raise my body temp at the beginning took me a bit to figure out.
-permanent upgrades might be fun so I can see how much further I can take it on my next run! Perhaps add a "distance" away from center as a score and procedurally generate some enemy bases and such or custom design it but make it feel expansive! I really like the setting of the game!
-Is there sound? It would add a ton if you get sound in the game! Wind howling, feet crunching in the snow!
-Make your bullets bigger. I can hardly tell when I am getting shot at and where my own bullets are going.
-I really like the art style of the game!
-I really liked the setting it felt like an arctic wasteland where I wouldn't know how far I needed to go to get to the next "base"
I assume all of this was done this month? Really great progress I think you can expand this into something great!
