First time player, so this is all new to me. Just reached day 48 <End of Alpha>, here's what stood out in terms of things to improve:
As has been said, coord radars are a problem. They chew through fuses too fast, with no upgrades like the transformers get to mitigate decay in-game. Fuses themselves are expensive to buy and there's not enough glass scrap available to reliably craft them.
Boars (or rather, the "combat" with the Boars) seem really out of place for the game's feel, especially since they apparently stick around forever, even after the failed siege on the treehouse. They're also very janky; half the time if you try to hook them to something, they zip into another dimension, with only a faintly heard explosion in the distance signalling their death.
The tutorial should really emphasize the importance of calibrating your satellites more. Or add a line mentioning it on the paper stuck to the server room's console, would help a lot.
Food fatigue is absolutely crippling for the first week, since MREs are all you really have. It also just doesn't really add anything in terms of enjoyment even when you can deal with it later on.
Would be nice if you could connect a hose to your power washer.
Even though toolboxes are cheap, it still doesn't feel great seeing your ATV wheels take so much damage from debris in the road and forest. Maybe add some sturdier wheels to the store or crafting list.
Finally, Kerfurs' pathfinding is wack. Not once was mine able to fix a single downed server without getting stuck on a corner or railing, or just "failing to find" the server. Maybe Omega is better, I never found out because bunker keycard is glued to the stairs.
