Some great points and there were supposed to be actual end turn mechanics for the game but the deadline got seriously near so i had to add an automatic chance-based system for the seeds, research, spare parts, new survivours, and the attackers.
there are 10 levels of upgrades for the walls.
as it's random-based logic sometimes you will have the luck other times you won't, i felt it made it play like it would be in a real situation, sometimes you get dealt a bad hand.
A playthrough i just today i managed to get so many spare parts and seeds but my research was low.
Focus on the food, there is a grace period until turn 20 where you don't get attacked and after turn 20 you might or might not get attacked, after the testing time for the GDTV game jam im going to add a small mechanic to allow you to beat an attacker if you are unlucky to have one attack.
Thank you for the constructive feedback.
