I'm glad that you liked the visuals (I spent half of the game jam making just that part + the performance optimizations).
Now afterwards I agree that the gameplay loop of walking from recharge station to the other is quite boring, maybe it would have been more interesting to have batteries laying on the ground or tossing the whole bomb thing asaide and having torch which would have kept you warm but made you easier to spot for the enemies.
The game would have probably been better if I had made it a linear game instead of an open world. The enemies (and probably players) would have had easier time navigating through the world (I tried using some fires to lure the player towards the end but not sure how well that went).
