A lot of fun! I love the pared-down RTS aesthetic, and seeing the fuel physically stack up at towers just makes me happy for some reason. I've only played the normal mode, and I do have to agree that it would be nice if you could "win" since it's possible, on Normal, at least, to pen in the frost rather than just survive (until all the trees are cut down, presumably). I feel like it would be nice if, once that condition is met, say if you detect that all the snow is gone, a quick calculation is done based on how many trees are left to determine roughly what the final score would be if you just waited it out. I assume in hard mode it's much more of a survival thing.
Anyway, immensely satisfying to watch all the interactions, and I think you did a great job! The customization mode gives it a lot of potential as something to load up from a USB drive during a boring meeting at work, lol
