Regarding the other points you raised: I'll take a look into the glitches and bugs you reported, and consider your suggestions. Thanks!
Regarding the S.O.S balancing: my plan is to have a day count in the game, and have main quest and side quests that need to be completed within some days limit. The S.O.S will cost you game-time, depending on how far you are from the last forklift you've been too.
I hope to release an updated version in a week or so.
